6.0 MiningPlanhasbeenpreparedtomine2.0MTPAironorebyopencastminingfully

mechanized method using shovel‐dumper combination. Stripping ratio has been

foundtobe1:0.16.Estimatedlifeofmineis14Years.

7.0 The iron ore produced from the mine will be consumed after dry beneficiation

blending & upgradation by the steel plants for commercial purpose as per the

auctionrulewithin&outsideofstate.

8.0 MiningMethod

Overburden will be removed & transported to external or backfilled area for

storage.Ironorewillberemovedbyblasting.

9.0 IronOreProcessing

Initiallyonlycrushingandscreeningoforewillbedoneatminesite.ROMgrade

ore as such cannot be sent directly to the plant. ROM ore will be subjected to

The +55% Fe will be upgraded by wet beneficiation outside the mining lease

boundarytoachievetherequiredgradeforsteelplant.



Considering300workingdays inayearand threeworkingshift, thesizeof the

mobile crushing& screening plant should be 2000000 tonnes ÷ 300 days ÷ 18

MethodofMining:‐

Beingahill‐topdeposit,Bhangaonironoreblockisamenabletoopencastminingby

fullymechanizedmethodwithafairlyhighdegreeofmechanization.

OpencastminingisidealfortheBhangaonIronOreBlockespecially,inviewoflow

OB/waste thickness and high iron ore thickness. Due to the gentle slope of the

BhangaonironoreBlock,theconventionalhorizontalbenchmethodofmininghasto

be adopted for this deposit.Mining fronts are planned to advance almost north –

South parallel to the surface contours & strike length of the ore. This will allow

miningof fullprofileof the ironore thicknesswith longer strike therebyenabling

blendingfromdifferenttop&bottomsections.



In order to take into account the interburden pockets of ferruginous clay

intersectioninbetweentheorezone,specialprecautionsneedtobetakentoavoid

dilutionoftheore.

The mine will be worked by fully mechanized opencast mining method. The

sequenceofminingoperationisgivenbelow:‐

4.6 SoilClassification

i) Reliable information on the location extent and quantity of soil & land

resources is the first requirement in planning for the sustainable

management of land resources. The components of land i.e. soil, climate,

water,nutrients&biotawhichprovideavarietyofservicesthatareessential

tothemaintenanceofthelifesupportsystemandproductivecapacityofthe

environment, knowledge of soil fertility status & problems of soil like soil

acidity / alkalinity become essential for development of a sustainable land

useplan.Fertilitystatusofthesoilisprimarily&importantlydependenton

boththemacroandmicro‐nutrientsreserveofthatsoil.

ii) The leaseareahasundulating topography.Thearearepresentsaveryhilly

iii) Micro‐Nutrients

Proper understanding ofmicro nutrients availability in soils and extent of

their deficiencies is the pre‐requisite for efficient management of micro‐

nutrients fertilizers tosustaincropproductivity.Therefore it isessential to

knowthemicro‐nutrientstatusofsoilbeforeanytypeoflanduse.

4.7 ClimateDatafromSecondarySources

The climate of this district is characterized by a hot summer, well distributedrainfall during the southwest monsoon season and mild humid post monsoonseason. The year may be divided into four seasons. The cold seasoncommences from December to February. The hot season from March to firstweek of June and themonsoon season is from June to September. October andNovember constitute the post monsoon season or transitional period betweensouthwestmonsoon andwinterseasons.

RAINFALLRecords of rainfall in the district are available for eleven raingauge stations forperiod ranging from 10 to 45 years. The details of the rainfall at these stationsand for the district as awhole are given inTables 1and 2. The average annualrainfall inthedistrict is1288.2mm.DuringthesouthwestmonsoonmonthsJuneto September the district receives about 82% of the annual normal rainfall.August is the rainiestmonthwithanaverage rainfallof327.0mm.Thevariationin the rainfall from year to year is large. In the fifty year period 1951 to 2000,the highestannual rainfallamounting to 144%of the normal occurred in 1956,while the lowest annual rainfall which was 62% of the normal occurred in2000. In the same fifty year period there were 8 years in which the annualrainfall in the district wasless than 80% of thenormal. However, noneofthemwere consecutive years. It is seen from Table 2 that the rainfall was between1001mmand1500mmin28yearsoutof45.On an average there are 65 rainy days (i.e. days with rainfall of 2.5 mm or

more) in a year in the district. This number varies from 57 atManjhari to 71

at Majhgaon. The heaviest rainfall recorded in 24 hours at any station in the

districtwas401.1mmatManjharion21June1977.



TEMPERATUREThere is only one observatory in the district located at Chaibasa. The records oftemperatures and other climatological parameters prevailing at this station may betaken to be broadly representative of the whole district. Temperatures begin todecrease progressively from November. December and January is the coldest partof the year with the mean maximum temperature at abour 25.8°C and the meanminimum temperature at 11.5°C. In association with cold waves, which affect thedistrict in winter months in the wake of western disturbances which move acrossnorth India, the minimum temperature may go down to about 4°C on individualdays.Temperaturesbegin to rise steadily after mid February till first week of June.May and early part of June before the onset of southwest monsoon constitute thehottest part of the year. In May the mean maximum temperature is at 39.3°C andthe mean minimum temperature is at 25.7°C. During this period, maximumtemperature may reach about 45°C on some days. The maximum temperaturedecreases andweatherbecomes appreciably coolwith the advance of the southwestmonsoon by about thesecond week of June and continues to be so throughout theseason. From November temperatures begin to decrease. The highest maximumtemperature and the lowest minimum temperature ever recorded at Chaibasa(observatory) were 46.7°C on 22 May 1948 and 4.4°C on 19 January 1934respectively.HUMIDITYThe summer months March to May are driest part of the year when the relativehumidity in morning is about 50% to 60% and about 30% to 40% in theafternoon. The air is humid in southwest monsoon season, when the relativehumidity is about 80%. During the rest of the year the air is generally dry andmildhumidwiththerelativehumidityatabout50%to70%.CLOUDINESSIn the winter andearly part of summer skies are generally clear or lightly clouded.However, on some days inthewinter in thewake ofwestern disturbancesskies areheavily clouded to overcast. The cloudiness increases from April to southwestmonsoon months, skies are heavily clouded or overcast. Cloudiness decreases fromOctober.WINDSWinds are generally light with slight increase in force in the latter part of summerand southwest monsoon season. In summer and southwest monsoon season windsare predominantlysouthwester1y. In the rest of the year winds arecalm.

SPECIALWEATHERPHENOMENA

Depressions originating in the Bay of Bengal during the southwest monsoon affectthe weather of the district and its neighbourhood during their northwesterly or



wester1y movement after crossing the coast. This causes gusty winds andwidespread heavy rain. Thunderstorms occur throughout the year except inDecember. Its frequency is more in latter part of summer and southwestmonsoonseason.Tables 3, 4 and 5 give normals of temperature and relative humidity, meanwindspeed andspecialweather phenomena respectivelyforChaibasa observatory.

GenerationofOB&Waste:‐

In this area the thickness of over burden is very low; this OB & sub‐grade ironore will be produced from the top benches. This produced sub‐grade will bestacked on the non mineralized area as shown on the plan initially & will beblended for utilization of sub‐grade ore in pursue of Mineral conservation.
