Condition of Threads - Threads should be inspectedbeforeinstallation.Increasedfrictiononthe threads adversely affects the torque tension relationship.

Fillet on Forged Head - Forged head rock bolts shouldbeinspectedtoensureafilletof1/8 " radius is present where the shaft connects to the forged head. Sharp transitions may weaken the bolt.

Hole Length - Holes too short for the bolt in use may cause the shell to distort or inhibit proper tensioningofthebolt.Goodpracticesuggeststhatthe hole length should be equal to the bolt length plus shell length.

Hole Condition - The hole should be cleaned and examined to ensure the bolt will insert smoothly. Damage to the shell may result if it must be forced into the hole.

Installation Quality Guidelines

Mechanical Rock Bolts

The following are items to be aware of when installing mechanical rock bolts (forged head and threaded both end [TBE] bolts):

Type of Ground - The nature of the ground must be evaluated. Soft strata requires a larger plate washer and/or expansion shell bearing area. Greaterexpansionoftheexpansionshellleavesmay be required. Soft ground results in larger hole sizes for a given bit size (bit rattling and reaming). Special anchors are available for soft ground. Excessively hard ground can be detrimental as well. Hard ground can result in poor anchorage as the shell is unable to “bite” into the rock.

Scaling - The ground should be thoroughly scaled i.e. barred down, before drilling and bolting. Periodic re-scaling may be required while drilling.

Strength and Yield Capacity of Bolt - The mechanical properties of the bolt should be appropriate for the ground conditions, bolt length and bolting pattern. Pull tests and torque-tension tests should be performed to determine yield strengths and anchorage capacities of the bolts being used.



Oversize Holes - Holes 1/8 " oversized can reduce holdingstrengthby70%.Oversizedholescanbecaused using the wrong bit size, leaving the drill running while �ushing the hole, soft ground (faults, gouge, etc.) and bent drill steel.

Undersized Holes - Undersized holes will not permit the plug in the expansion shell to seat properly. The leaves or bail can break and distort upon forced entry. Undersized holes are usually caused by worn bits and/or wrong bit sizes being used.

Friction Flair Expansion Shells - A recent improvement in expansion shell design is the addition of �airs or wings on the bail strap at the bottomoftheleaves.Installationisimprovedasthere is no need to set the anchor to keep the bolt from sliding out of the hole during installation. The anchor sets up faster as the plug engages the leaves freely. Spinning of the anchor in the hole is prevented, thereby eliminating the principal cause of bolt failure upon installation.

Resin Anchors - Using a resin cartridge to assist in anchoring mechanical rock bolts is gaining popularity.Ifusedwithanexpansionshell,theshell must have provisions for the passage of resin around the shell wedge. This ensures proper encapsulation of the expansion shell without causing any damage to the assembly.

Expansion Shell Plastic Sleeve - The plastic sleeve holding the leaves together on an expansion shellshouldberemovedpriortoinstallation.Iflefton it could result in poor anchorage.

Set Up of Expansion Shell-Immediatelypriorto installation the expansion shell should be set to the correct diameter to enable the bolt to be pushed up the hole by hand, set and anchored. If notexpandedenoughtherewillbedifficultiesinanchoring.Ifexpandedtoomuchtheendofthebolt can break the bail or leaf attachment prior to the leaves being set.

Installation Quality Guidelines continued



bolt dollies have a 7/8" hex shank and are only 31/4" long.Inadditiontobeingthepropersizefortherock bolt head or nut, the dolly must also have sufficientsocketdepthtoallownutstoberunontothe ends of TBE bolts.

Proper Torquing of Bolts - Typically, 3.5 tons of installed tension is required for a rock bolt to set the anchor and tension the bolt to 50% of the yield strength. An approximately linear relationship exists between the applied torque and the tension in a forged head rock bolt.

continued


DSI - Mining’s T-Dome - forged head rock bolts have a special concave head design which when used in conjunction with T-Dome plates, work like a ball-and-socket and correct for angularity without requiring extra washers.

Rock Bolt Dollies - Rock bolt installation dollies should only transfer rotational energy to the rock bolt during installation, not percussive energy, when stopers and jacklegs are used. The shank end of the dollie must be short enough to avoid contact with the drill piston. Typically, these rock

As TBE bolts turn at both ends during torquing, they generally apply more tension for the same amount of applied torque due to the reduced resistance to friction. However, as a generality:

All mechanical rock bolts should be torqued to a minimum of 150 ft-lbs (per ASTM F432).



the placement and spacing of bolts. Torque measurements can be recorded on the wall or plate of the bolt which will permit monitoring of theloadontheboltduringtheminingcycle.Ifnecessary, bolts can also be re-torqued if loss in tension occurs. Torque testing is best done by a crew supervisor (or dedicated technician) while visiting work areas during his rounds.

Education - Proper education of mining personnel and supervisors is mandatory. As manpower turnover is relatively frequent in bolting crews, education must be continuous. Forget this and you waste money.

Packaging - Vendors must package bolting products in an acceptable manner both for con-venience of use as well as prevention of damage to the product during shipping and handling. Particular care must be paid to wrapping of the thread ends to prevent damage and corrosion. Goodpackagingcostsmorebutisworththeadded cost by reducing wastage on site.

continued


Overtorquing-Overtorquingoftheboltsmustbe avoided. With forged head bolts, the heads canbeweakenedorshearedoff.Overtorquingmay tension the bolt past it’s yield point which is undesirable.

Undertorquing - Undertorquing can result in poor anchorage. Under tensioned bolts are particularly susceptible to blasting damage. Bolts will not applysufficientcompressiveforcetothegroundas per design requirements.

Monitoring-Inpractice,rockbolttensionoftendrops after installation. Expansion shells can slip due to blasting vibrations, shells can move as high stress concentrations along the leaves cause localizedfailureoftheground,andfinally,therockcan fail under the plate washer.

The installation of any ground support system must be monitored to ensure proper procedures and installation quality are maintained. For rock bolts this requires verifying torque and



Matching Bolt and Shell Threads - While North American mines typically use UNC thread specs, other countries can use different thread types. Care must be taken not to mismatch shells and bolts from various manufacturers. A minimum UNC class 1A thread spec should be met on allthreadsasperASTMF432guidelines.DSI-Mining exceeds ASTM specs and rolls threads to a class2Aspecification.

Support Nuts - While they are sometimes used on TBE bolts, the practice of installing a nut below the anchor shell should be avoided on forged head bolts.Ifthesupportnutcomesincontactwiththe shell, friction between these two surfaces will prevent the bolt from elongating properly and will give false torque readings as the bolt is tensioned. Headed bolts should be free to elongate into the hole through the expansion shell.

TBE Bolt Nuts - Do not run the nut on a TBE bolt to the end of the threads and onto the shank. Strength can be reduced by as much as 50%. Each revolution of the nut onto the shank reduces the thread engagement length.

Notching of TBE bolt threads - Notching threads on TBE bolts is a poor installation practice and must be avoided. This practice locks the nut onto the bolt which then makes the TBE bolt act as a forged head bolt. Deep gouging can reduce the bolts strength.

Proper Grade Plates - Thin or weak plates will deform at low bolt tension. High torques will produce lower tension values. The bolt could also rip through the plate during installation or by bolt loading. Plate should meet ASTM F432 specs. The minimum spec is a grade 2 plate which has less than 0.25 de�ection when the load on the plate is increased from 6,000 to 20,000 lbs.

Hardened Steel Washers - Hardened steel washers should be used between the forged head or nut and the plate washer. The washer reduces friction and enhances the torque-tension relationship. Minimum grade should be Type 2 (ASTM F432 spec) and hole size in plate washer should be no more than 3/8" diameter larger than bolt size. A spherical seat washer can also be used to reduce friction.

Wooden Washers - Although seldom used nowadays, wooden washers help prevent the plate from cutting into mine screen (mesh) when present. The wood may cause tension bleed off however. Care must be used to watch for rotting of the wood.

Perpendicular Installation - Bolts should be installed as near perpendicular to the rock surface as possible. Bolts not perpendicular to the plate and rock surface will be marginally weaker and will not be pretensioned properly. The following example using a 5/8 " forged head rock bolt installed with 180 ft-lbs torque illustrates the scope of the problem.

The Wedge Anchorage of the Cable Bolt

The anchorage of most cable bolts consists of a wedge barrel and a 2- or 3-part wedge. The wedge segments grip the cable by means of tooth shaped threads which are forced into the surface of the cable wires.

Warning:Iffrictionincreases(duetocorrosion),a larger F will reduce the clamping force. As V increases all other forces can only increase if thewedgecanseatdeeperintothebarrel.Ifthewedge is restrained to do so (i.e. by corrosion or dirt-accumulation), the clamping force can not increase with the pulling force causing slippage when the load on the cable bolt gradually increases during service life.

To avoid slippages during use, it is important that the cable bolt is fully stressed at time of installation to a force equal to 0.5 Fu. (i.e. 50% of the capacity of the cable)

The clamping force W is highly dependent on the friction between wedge and wedge hole. For normal friction conditions, the clamping force W is more than 4 times the cable pulling force V and it adjusts with the pulling force V.

When a wedge is properly seated, radial cracks may develop indicating adequate seating.

ThewedgecanbesuppliedwitharubberO-ringor a metal spring ring holding the wedge segments together.

Undersize Holes-Iftheholesizeistoosmallrelative to the friction size then it becomes extremelydifficulttoinstallthebolt.Theboltcanbe damaged i.e. kinked or bent when installed. Undersized holes are usually caused by worn bits and/orwrongbitsizesbeingused.Ifintegralsteelis used with a stoper or jackleg, the hole diameter decreases with each change of steel (normal practice requires smaller bits be used as one drills deeper into the hole). With each reduction in hole diameter the anchorage capacity increases. Integralsteeloftenresultsincrookedholesandshould be avoided whenever possible.

Drive Times - For a typical 5 or 6 foot friction bolt, a stoper or jackleg will drive the bolt into the hole in 8 to 15 seconds. This drive time corresponds to proper initial anchorages of the stabilizer. Faster drive times should serve as a warning that the hole size is too large and thus the initial anchorage of the bolt will be too low. Longer drive times indicate smaller holes sizes probably caused by bit wear.

continued



The following are items to be aware of when using/installing friction stabilizers:

Type of Ground - The nature of the ground must be evaluated. Soft strata requires a longer anchorage length to be effective. Soft ground results in larger hole sizes for a given bit size (due to bit rattling and reaming).

Scaling - The ground should be thoroughly scaled (i.e. barred down) before drilling and bolting. Periodic re-scaling may be required while drilling.

Strength and Yield Capacity of Bolt -The mechanical properties of the bolt should be appropriate for the ground conditions, bolt length and bolting pattern. Pull tests should be performed to determine initial anchorage of the friction bolts.

Proper Grade Plates - Thin or weak plates will deform at low bolt tension. The bolt could also rip through the plate during installation or by bolt loading. Plates should meet ASTM F432 specs.

Hole Condition - The hole should be cleaned and examined to ensure the friction bolt will insert smoothly. Variation in hole diameters (due to differing strengths of rock strata or excessively fragmented ground) can yield variations in anchorage capacities at various elevations.

Hole Length-Ifholesaredrilledtooshortthenthe bolt will stick out of the hole and the plate will not make contact with the rock surface. Damage to the bolt will result if an attempt is made to drive the bolt further than the hole length will permit. The hole should thus be a few inches deeper than the bolt length being used.

Oversize Holes - The hole size required for the friction stabilizer is the most crucial aspect of the installation. The holding power of the bolt relies on the fact that the hole is smaller than the diameter of the bolt. The larger the hole relative to the bolt diameter, the less the holding force (at least initially).Oversizedholescanbecausedbyusingthe wrong bit size, leaving the drill running while �ushing the hole, soft ground (faults, gouge, etc.) and bent steel.



Bit Selection - Button bits are commonly up to 2.5mm larger than their slated size. A 37mm button bit may in reality be 39.5mm in diameter when new. This is too large for an SS- 39 friction. Button bits do wear quickly however, increasing anchorage capacity and increasing drive times. Crossor“X”bits,ontheotherhand,aresizedtrueto stamped size usually within 0.03". They hold their gauge very well but tend to drill slower than button bits. They are preferable to button bits for friction installation where possible.

Perpendicular Installation - Bolts should be installed as near perpendicular to the rock surface as possible. This ensures the welded ring is in contact with the plate all round. Bolts not perpendicular to the plate and rock surface will result in the ring being loaded at a point which may cause early failure. Unlike other rock bolts, spherical seat washers are not available to correct for angularity with frictional stabilizers.

Installation Driver Tools - Driver tools must transfer percussive energy to the bolt during installing, not rotational energy. This is opposite to most other forms of ground support. The shank end of the driver must be the proper length to contact the drill piston in stopers and jacklegs (i.e. 4¼" long for 7/8" hex drill steel). The shank end on the drivers is round so as to not engage the rotation of the drill. The driver tools must have the properendshapetofitintothefrictionwithoutbinding and causing damage to bolt during installation.

Education - Proper education of mining personnel and supervisors is mandatory. As manpower turnover is relatively frequent in bolting crews, education must be continuous. An informed workforce will save money in the long run.

Monitoring-Installationmustbemonitoredto ensure proper procedures and quality are maintained. Pull-test measurements should be routinely conducted on friction stabilizers to check initial anchorage values.

Fillet on Forged Head Rebar - Forged head rebar boltsshouldbeinspectedtoensureafilletof1/8" radius is present where the shaft connects to the forged head. Sharp transitions may weaken the bolt.

Shelf Life of Resin - Resin has a practical shelf life. Although the chemical ingredients do not change with time, most resin cartridges are water based and thus dry out with age. The shelf life thus refers to the workability of the resin cartridge. Aged cartridges are still effective; however, because they are drier, the ingredients are crumbly and harder to mix properly. The bolts are moredifficulttoinsertthrougholdresinaswell.Set times may also be reduced somewhat with older resin. The resin cartridge box will have the manufacturing date written on it. Resin should be used as soon as possible. Stock should be rotated so older resin does not accumulate.

Storage - Resin should be stored in a cool location to maximize shelf life. Elevated temperatures dry out the resin cartridges.

Temperature and Set Time - Temperature greatly affects the gel (set) time of resin cartridges. A 20ºF rise in temperature reduces the set time by approximately 50%. Conversely, a 20ºF drop in temperature will approximately double the set time of the resin. Resin should be stored and used at room temperature whenever possible.

Rebar and DYWIDAG THREADBAR® Bolts

The following are items to be aware of when using/installingresingroutedrebarandDYWIDAGrock bolts:

Type of Ground - The nature of the ground must be evaluated. Soft strata requires a larger plate washer bearing area and a longer anchorage length if point anchored. Soft ground results in larger hole sizes for a given bit size (due to bit rattling and reaming). This can adversely affect the mixing of the resin.

Scaling - The ground should be thoroughly scaled i.e. barred down, before drilling and bolting. Periodic re-scaling may be required while drilling.

Strength and Yield Capacity of Bolt - The mechanical properties of the bolt should be appropriate for the ground conditions, bolt length and bolting pattern. Pull tests should be performed to determine yield and ultimate strengths of the bolts as well as resin anchorage capacities.

Condition of Rebar Threads - Threaded rebar shouldbeinspectedbeforeinstallation.Increasedfriction on the threads can adversely affect tensioningoftherebar.DYWIDAGthreadsaregenerally immune to defects and damage.



Resin Size, Bolt Size and Hole Size - The size of the bolt relative to the cartridge and hole size is critical. The above chart gives the recommended combinations of bar, hole and cartridge sizes. The numbers in the chart refer to the yield i.e. length of encapsulation of the bolt per 12" resin cartridge. Blank spaces are non-recommended bolt and hole combinations.

Hole Condition - The hole should be cleaned and examined to ensure the resin cartridges and the rock bolt will insert smoothly.

Hole Length-Ifholesaredrilledtooshortthenexcessive lengths of the bolt will stick out of the hole. The plate may not be effectively installed. Ifholesaredrilledtoolongthenresinwillbewasted at the end of the hole. This will reduce the encapsulation length for a point anchored rock bolt and can reduce the load capacity of the bolt. The bolt may not be able to be tensioned adequately.

Oversize Holes -Iftheholesizeistoolargerelative to the bolt size, poor mixing of the resin will result. The grout yield per resin cartridge will also be reduced. This is particularly important withpointanchoredbolts.Oversizedholescanbe caused by using the wrong bit size, leaving the drill running while �ushing the hole, soft ground (faults, gouge, etc.) and bent drill steel.

Undersized Holes - Undersized holes will result ininsufficientbondingofthebolttotherock.Difficultiesininsertingtheboltintotheholemayalso be experienced. Undersized holes are usually caused by worn bits and/or wrong bit sizes being used.

Spinning of the Bolt - refer to Resin and Cement cartridge section (Section 9).

Underspinning - The bolt is spun into the resin cartridge to mix the two separate components (the catalystandtheresinmatrix).Impropermixingwillresult in a poor installation. Underspinning results ininadequatemixingoftheresinandinsufficientgellingmayoccur.Operatorswillcomplaintheresin will not set up.

No Spinning-Iftheboltissimplypushedthroughthe resin cartridge without rotation, a detrimental effect may be caused by the resin catalyst being picked up by the end of the bolt. This may cause both undercatalysed and overcatalysed areas to be created.

Overcatalysedresinyieldsanunderstrengthcrumbly type of anchor. Undercatalysed resin stayssoftvirtuallyindefinitelybecauseitdoesnot have enough catalyst to speed up the gelling reaction.

Overspinning-Overspinningwillgrinduptheresin as it sets. Poor anchorage will result. The bolt may not be able to be tensioned properly. Consequently, the operator will once again complain the resin is not setting up!

Tensioning with Fast/Slow Set Resins - As a general guideline, when bolts are to be tensioned, fast set resin should be used at the toe of the hole for 1/3" the bolt length (minimum 24"). Slow set resin is used for the remaining 2/3" length to fully encapsulate the bolt. The slow set must be sufficientlyslowtoallowtheplatewasherandnut to be installed and the bar tensioned before the resin set up. Rebar bolts can be tensioned by torquingthenut.DYWIDAGboltsrequireagreatertorque to achieve adequate tension.

continued




Proper Grade Plates - Thin or weak plates will deform at low bolt tension. The bolt could also rip through the plate during installation or by bolt loading. Plates should meet ASTM F432 standards.

Perpendicular Installation - Bolts should be installed as near perpendicular to the rock surface as possible. Bolts not perpendicular to the plate and rock surface will be marginally weaker and will not be pretensioned properly. Spherical seat washers are available to correct for angularity.

Hardened Steel Washers - Hardened steel washers should be used between the forged head or nut and the plate washer. The washer reduces friction and enhances tensioning in threaded rebar. Minimum grade should be ASTM F436 Type 1 or 2 and hole size in plate washer should be no more than 3/8" diameter larger than bolt size if a spherical seat washer is not used.

Rock Bolt Dollies-Installationdolliesshouldonly transfer rotational energy to the bolt during installation, not percussive energy when drills are used to rotate the bolt. The shank end of the dollie must be short enough to avoid contact with the drill piston in stopers and jacklegs. Typically, these rock bolt dollies have a 7/8" hex shank and are only 3¼" long. Besides being the proper size for the rock bolt head or nut, the dolly must also have sufficientsocketdepthtoallownutstoberunontothe threaded portion of the bolt.

Gloves-Glovesandeyewearshouldbewornwhen handling resin.

Odour - Polystyrene monomers in the resin have a particularly noticeable smell. Properly installed bolts (i.e. properly set up resin) will have no odour. The smell of styrene underground implies broken cartridgesattheworkplaceorinsufficientlymixedresin in the hole.

Education - Proper education of mining personnel and supervisors is mandatory. Resin anchored bolts in particular require skilled miners. As manpower turnover is relatively frequent in bolting crews, education must be continuous. Forget this and you waste money.

Monitoring-Installationmustbemonitoredto ensure proper procedures and quality are maintained. Pull-test measurements should be routinely conducted on resin anchored bolts. Torque measurements can also be taken on threaded rebar bolts and monitored for changes. Torque testing is best done by a crew supervisor (or dedicated technician) while visiting work areas during his rounds.

Packaging - Vendors must package bolting products in an acceptable manner both for convenience of use as well as prevention of damage to the product during shipping and handling. Particular care must be paid to wrapping of the thread ends to prevent damage and corrosion. Resin cartridges must be robust so as to not rip or tear during normal handling. Good packagingcostsmorebutisworththeadded cost by reducing wastage on site.

DCP Bolt

Typical Installation Procedure

DescriptionTheDSIDoubleCorrosionProtectedBolt(DCPBolt) is a pre-tensioned & post-grouted rock bolt. Itallowsforimmediategroundsupportusinganexpansion shell and has a high density corrugated polyethylene (HDPE) sheath along the bar length that provides long term corrosion protection and load transfer. The system can also be provided with triple corrosion protection (TCP Bolt) using special anti-corrosion bars, galvanizing or epoxy-coating.

ComponentsThe DCP Bolt comprises a 7/8" diameter steel bar pre-assembled with an expansion shell, corrugated polyethylene (HDPE) sheath attached to a grouting bell and domed hex nut (36mm A/F). The nut is slotted for post-grouting. The required dome plates are supplied separately and are generally ASTM F432 grade 2 or 3 material.

Bolt HandlingDCP bolts must be kept clean at all times. Care must be taken not to damage the HDPE sheath, grout bells and expansion shells during shipping and handling.

DrillingDepending on the size of the expansion shell, drill either45mmor50mm(1¾" or 2") holes the total length of the bolt plus 50mm (2"). Thoroughly �ush the hole with water after drilling. Ensure that the bearing surface for the dome plate is within ± 15 degrees from being perpendicular to the bolt.

DYNA® Tork Bolt

DYNA® Tork bolt is designed with a spiral mixing bladetoensureultimatemixingofDSIresinintheborehole. This blade design has a dual propose: to mix the resin properly and provide anchorage for static ground support. The cone is designed to yield and transfer dynamic loads into the resin in rock burst conditions, absorbing the energy through controlled deformation. This ploughing effect through the resin will ensure that most of the kinetic energy in a rock burst is contained within the rock-mass. The DYNA® Tork bolt is the ultimate Dynamic Rock Support Solution for deep mining where it provides proper anchorage in a regular static mining environment, and ultimately yielding support in dynamic rock burst conditions.

DYWI® Drill Self-Drilling Bolt

TheDYWI® Drill Self-Drilling bolt is a fully threaded hollow bar that initially serves as a drill rod, utilizing a lost bit. The thread is made to 15010208. For use inunconsolidatedgroundorotherdifficultgroundconditions.

Excellent for spiling (fore-poling).

Bolt is drilled in and grout is pumped through the center hole with pumpable resin or cement grouts.

The couplers are designed to exceed the ultimate load of the bar by 20%. The couplers are designed to minimize the loss of drill energy.

Several drill bits are available. Most widely used is theEXXTungstencarbidechiselbitforhandlingUCT*upto12.5N/mm²(RQD100%)andupto50 N/mm²(RQD75%).

Standard length is 3m (9ft-10"). Longer lengths are available: 4m, 6m

*UCT is uncon�ned compressive strength

DSIHollowBarSystemistypicallyinstalledusingrotary percussive drilling. This technique enables high rates of installation, good directional stability and also helps to consolidate the grout within the borehole.

Rotationspeedsshouldbesufficienttocutatrueborehole (120-150 RPM for soil nails; 100-130 RPM for mini piles), as opposed to displacement of the soil with the drill bit through percussion and heavy feed pressures (driven installation). Drilled boreholes ensure enlarged grout bodies together with better permeation of the grout into the surrounding ground. Feed pressures on the drill rods should be regulated in accordance with the cutting performance of the drill bit.

Simultaneous Drilling and GroutingSuitableforgranularsoilsandfills.ThisinstallationmethodutilizesaGroutSwivel,groutpumpand drifter. The technique combines drilling and grouting as a single operation, ensuring that grout

is placed over the full length of the borehole. For ground conditions where borehole collapse is anticipated or where subsequent grout injection down the center of the bar is problematical, simultaneous drilling and grouting is the preferred solution.

Groutingpressuresshouldberegulatedtomaintain circulation at all times (typically up to 100 psi), with a small amount of grout return visible at the mouth of the borehole. Pressures in excess of 100 psi are generally only required for specialist applications (i.e. anchors in cohesive soils or mining applications).

The choice of grout pump varies between applications, but basic requirements are as follows:

a) thorough mixing of the grout – to avoid blockages at the drill bit,

b) delivery of a continuous volume – to ensure consistent grouting,

c)maintenanceofsufficientpressure.

Directions For Use1. Hole Preparation The holes should be drilled with rotary

percussion type equipment such that the hole side walls are not smooth. The drill hole must be clean and free from debris, oil and grease. The hole should be dry, but a good bond can be obtainedinwetorunderwaterholesifsufficientsidewall deformities exist.

2. Mixing Instructions Note the pot life-temperature relation and

proceed by suspending all solids in the grout followed by adding the cup(s) of hardener to the mixing pail of grout and stirring the mixture as rapidly as feasible until no streaking of the

hardener is observed in the grout-hardener mixture. The proper ratio is obtained when all of the hardener is added to the grout. UNDER NOCIRCUMSTANCESshouldanyforeignsubstance be added to the grout-hardener mixture.

3. Installation Pour the grout-hardener mixture into the drill

hole to a level about 2/3full.Insertthedoweloranchor bolt and work it back and forth to avoid airentrapment.Assumethefinalpositionofthedowel or anchor bolt, top up the hole with liquid grout and allow the grout to gel in that position. The grout will gel in one and one-half times its pot life at the given temperature. Working loads can be applied in six times the pot life.

4. Cleaning Cleaning of tools, spills or runs is best

accomplished before the grout has hardened by wiping off excess and further cleaning the surfaces with acetone (propanone), or another type of high grade mineral spirit, making certain that the surface is compatible with the spirit used. Remove empty containers from the job site and dispose of according to area regulations.

5. Caution This product is intended for industrial use

only. Avoid contact with eyes and prolonged contact with skin. Use protective measures. Incaseofeyecontact,flushwithwaterforatleast15minutes.Ifirritationdevelops,contacta physician.

FASLOC® Resin Cartridges

Polyester Resin Anchoring System

DescriptionTheFASLOC® resin in the cartridge is used to anchor bolts to the surrounding strata. This unificationoftheresin,boltandstratalayersprovides the necessary strength and rigidity to prevent sag by acting as a reinforcement which anchorstheindividualstratifiedlayersofrockintoa single high strength beam.

The two-compartment cartridge shown in illustration A above consists of a heat-sealed tubeofpolyesterfilmclippedatbothends.Onecompartment contains a dark gray resin; the other, a light gray catalyst. A cross section of the cartridge is shown in illustration B.

Afilmbarrierofheatsealedpolyesterfilmpreventsmigration between the resin and the catalyst to provide optimum shelf life. The excellent chemical resistanceofthefilmminimizesmigrationfromtheinside and the absorption of contaminants from the outside.

B. CROSS SECTION

The light-weight, dimensionally stable casing of filmisstrongenoughtowithstandroughhandling,but shreds quickly and thoroughly during the installation procedure.

FASLOC® is thixotropic and fast setting. This reduces viscosity during insertion of the bolt and permits relatively low installation force and torque. The results are fast installation, rapid achievement of full strength, and a minimum tendency for ungelled resin to drip from the holes during installation.

General Installation Instructions•Theinstallationproceduresshouldbefollowed

carefully to ensure successful application of FASLOC® resin grouting.

•Variousfactorsaffectinstallation.Theseinstructions are general guidelines. Mine tests must be conducted with bolts to determine actual “mix” and “hold” times.

•Boltsshouldbeinstalledassoonaspossiblein newly-exposed roof. Roof that has shifted or sagged offers least chance for successful support.

•Donotuserupturedorbrokencartridges.

•RefertoM.S.D.sheetsandProductBulletinforadditional technical and safety data.

Safe Handling PrecautionsCaution: Do not open or puncture cartridge. Physical contact with liquid contained in cartridge may cause mild irritation. Safety glasses or eye shield should always be used when roof bolting isdone.Incaseofeyecontact,immediatelyflushwith plenty of water for at least 15 minutes. Call a physician.

Incaseofskincontact,flushskinwithwater.Prolonged contact with skin may cause mild irritation.Irritationshouldsubsidewhenmaterialisremoved.

4aFullyGroutedBoltsPush the bolt upward with the maximum thrust available from the machine and hold untilFASLOC® hardens. Do not rotate after Step 3. Damage to partially gelled resin may result.

3 Rotate the bolt as indicated above.

4c Resin Point Anchor BoltsWhenFASLOC® is used to supplement mechanical shell anchors, spin-to-lock.

4b Tension Rebar & Combination BoltsHold the bolt until the resin has hardened. This period of strength development will vary depending on gel time, product temp. and mine conditions. When resin has hardened, rotate the bolt until the desired torque is developed.



UsesFASLOC® has been a leading supplier of polyester resin cartridges to the mining industry for over 30 years.FASLOC® resin cartridges allow for quick and reproducible anchoring of many varieties of boltsandcables.Inmineroofsupport,FASLOC® systems reinforce strata, providing strength and rigidity in untensioned systems, and ensure a durableanchorageforFASLOC® resin grouted tensioned bolts. The reinforcement technique bondstheindividualstratifiedlayersofrockintoasingle,highstrengthbeam.FASLOC® resin cartridge can also be used in many other reinforcement, stabilization, and anchoring applications. The reliability of the anchorage system, plus ease of use and minimal resin setting times, will increase productivity and safety.

AdvantagesTheproprietaryFASLOC® package has a distinct advantage over other resin systems due to:

• Highcatalyst/resinratio• Uniforminstallationtime• Mixingefficiency

Cartridge DiametersNominal diameters for both imperial and metric are available. Diameters are as follows:

Cartridge LengthsCartridges are available in lengths from 12" to 60".


Storage RecommendationsFormaximumshelflife,FASLOC® cartridges should be stored away from direct sunlight in a reasonably cool, well-ventilated, dry area. Storage life is up to 1 year, depending on ambient temperature conditions. Under adverse conditions shelf-life is reduced. To ensure proper storage, the product should not be subjected to temperatures in excess of 85°F for prolonged periods. Storage is recommended under cover, on original pallets withadequateventilation.Ifstoredintrailersinhotweather, door should be left ajar or a sun screen erected over the trailer. Conversely, while cold storage does not adversely affect the shelf-life of FASLOC®, it should be warmed to a range of 50°-60°F before using to assure gel times within the specifiedrange(seeFigure2).

ThetimerequiredforcasesofFASLOC® to warm or cool to ambient temperature is dependent on both the initial temperature and how the cases are stacked. Where the initial temperature is anywhere between 25° and 85°F, cases will come within 5° of ambient temperature in 48 hours when stacked in single columns with 4 sides of each case exposed to the air. Multiple columns should be separated by at least 2" to assist air circulation between columns.

Shotcrete Mesh Panels

Advantages•Fastandeasytoerect•Non-corrosiveifgalvanizedmeshisused.•Concussion-resistant

Shotcrete Mesh Panels are constructed with black or galvanized mesh and burlap cloth. Stiffeners are incorporated for three-dimensionable stability. The panels can be various sizes depending on application. They are lightweight and can be cut-to-shape with small bolt-cutters. When Shotcrete is applied to the panels, the result is a durable wall, which is resilient to close proximity blasting.

Star Plate Speci�cationsThe most important features of any roof plate are stiffness, yield strength and area of contact with the rock, especially under high loads.

TodeterminetheseparameterstheDSIResearchand Development team have developed a testing method which very closely simulates underground coal mining conditions.

Figure 1 illustrates the performance of the new Star Plate (and compares it with other common roof plates) for conditions commonly encountered in Australian underground coal mines. The Star Plate yield load is close to the yield strength of the mostwidelyusedAXtypebolt.

Apart from the high strength of the Star Plate (despite its relatively thin plate thickness of 5mm) it has the additional advantage of providing a larger bearing area when heavily loaded as shown in Figure 2.

TheStarPlateisafurtherexampleofDSIResearch and Development Team’s world leading technology in Strata Reinforcement Products, that seeks safe, cost-effective solutions for the underground mining industry.

VTS Props

The Salzgitter Hydraulic Props, now produced byVTSandmarketedinNorthAmericabyDSIUndergroundSystemsInc.,offersafetyontheface. They can be easily maintained and operated, and, according to the requirements and depending on the prop type, readily extended with slip-on extension pieces.

The VTS Props are set by hydraulic pressure pump and fed into the setting gun via a setting line installed in the face. The setting gun will be put on thefillingvalveoftheprop,mechanicallysecuredwith a one-hand locking mechanism, and operated by one hand.

The pressure �ows through the setting gun and fillingvalveintotheinteriorofthepropandcausesthe internal prop and the piston to telescope. After having been set against the support (articulated bar) the prop is braced with the setting force existing in the setting line, thus immediately supporting the roof.

Due to the rock pressure the prop can now be loaded till the set pressure on the operating valve willhavebeenreached.Ifthenominalpressureisreached, the operating valve will open and some hydraulic �uid will be sprayed off till a pressure spring will close the operating valve again. This process repeats itself every time the nominal pressure is reached. Thus, the prop remains always protected from overload by the rock pressure.

Large lifting heights permit a large range of convergences.

Due to the possible extensions according to the prop types, the prop length can be readily adapted underground to the changes of the face heights.

The prop can be withdrawn with a releasing key that — extended by means of a rope or a chain — actuates the releasing valve from a safe place of the miner and lets the hydraulic �uid escape from the cylinder. An installed return spring rapidly retracts the internal prop. Herewith, the prop is ready for use again for a new setting operation.

Steel 4-Flange Liner Plates

DSIUndergroundSystemsInc.selectionofunder-ground supports, the widest in the world, affords the contractor, the designer, and the owner a matchless combination of high performance and tunneling at low cost.

tunnel is straight, curved, circular, elliptical or horseshoe in shape.

•Gasketplatesthatsealjoints,stopwaterleakage and reduce air loss when water is a problem.

Steel liner plates provide a relatively light-weight, easy-to-handle, safe support for soft ground tunneling because the ground that supplies the loading also supplies the resistance to the load. The liner plate assembly simply distributes and transmits the load to the surrounding earth. As a steel liner plate ring takes load vertically, it tends to de�ect inward at the top and outward at the sides. The ground resists de�ection of the lining by developing a passive force equal in magnitude and opposite in direction to the force exerted by that of the lining. The diagram on the left illustrates this principle.

The ability of the surrounding ground to resist the outward bulge of the liner plate ring is the key toverticalloadsupport.Withtheringconfinedto a small amount of de�ection, the thrust line induced by the load is forced to follow the ring of liner plates. Thus, the ability of the assembly to withstand the applied load depends upon its ability to transmit ring thrust from plate to plate aroundthering.Obviously,thisabilityisenhancedbythefour-flangedesignofDSIUndergroundSystemsInc.plates.

There are various methods for determining the required strength of tunnel linings. Nevertheles, the type of ground, the location and depth of cover, the size and length of the tunnel, level of ground water, superimposed loading, and history always guide these calculations.

DSIUndergroundSystemsInc.linerplatescanbepurchased in 16" and 24" widths as corrugated or smooth plates. Liner plates are formed from one piece of metal to provide longitudinal and circumferential �anges. The plates can be galvanized and/or bituminously coated and grout holes with plugs can be included. For special conditions gasketed liner plates and tapered liner plates can also be manufactured. Liner plates can be installed alone or in conjunction with steel ribs if additional support is required.

Typical Liner Plate Installations

Liner Plates OnlyThe most obvious advantages of this structure are that maximum support per foot of tunnel is obtained with minimum weight of steel. Liner plates, properly groutedorbackfilledastunnelingprogresses, form a dependable structure in either cohesive or non-cohesive ground. Liner plate structures generally require no additional support in tunnels up to 14' in diameter.

Ribs Inside Liner PlatesTo give extra support to a liner plate structure in large diameter or heavy load conditions, ribs can be added inside the ring. Liner plates then act as lagging and are normally lighter in gage.

This additional support usually requires an increase in the diameter of the driven bore to maintain the dimensions of the finishedinsidediameter.Thismethod is often used in shaft construction.

Liner Plates Between RibsThis type of structure is less common than ribs inside liner plates because it is harder to erect. Itdoesofferapracticaltrade-offunder certain tunneling conditions.

Three basic ways sof installing plates in tunnels or shafts are illustrated here; each has its advantage in a particular application or ground condition.
