3. TOPOGRAPHY AND GEOLOGY
Topography:
The lease area is falling in the river bed Hasdo. The sand found in river bed.
The general surface level of the lease area is comparatively lower than the
surrounding. The general surface level is around 702m RL on the river bank.
The drainage location is towards south direction in the lease area.
River and drainage:
The lease area forms the river bed of Hasdo River which flow towards south
direction in the lease area. Hasdo has its origin in the hills of Sonhat Tehsil.
The Hasdo River is the tributary of Mahanadi River. It has large catchment
area.
Transportation of sand :
The sand is not an in-situ material. It is being carried out by flowing water
during the monsoon every year from various catchment area in Koriya district
and getting accumulated at convenient location like bends, escarpments etc.
And as such the sand of the lease area is a carried material brought from
various locations and getting accumulated at convenient places in the flow
direction from the river. The size of the accumulated sand varies due to the
time factor taken by the river as well as the quantity of low water. The
depositions normally take place on winding course
(bend)/meanders/loops/circuitous journey (of a river) in flow direction.
Regional Geology
The state of Chhattisgarh constitutes one of the important geological terrains of
the Indian Shield exposing rock sequences from Archaean to Recent.
A crustal scale Central Indian Shear Zone (CIS) trending E-W and passing
through the central part, subdivides the state into two distinct geological
provinces viz., the southern Bastar province and the northern Satpura
province.

Notified Sand mine area is geologically situated in the bed of Hasdo River in
Koriya district predominantly comprising older sandstone, exposed forming
bold and rugged topography represented by high hillocks and undulatatory
terrain. Part of the area is peneplained, weathered and extensively occupied by
the alluvial sandy soil cover ranging from 0 to 5m.
Notified sand mine area is geographically situated in the river bed of Hasdo. In
eastern part of almost horizontally bedded Gondwana supergroup comprised of
the equivalent of sandstone of Barakar formation. Rocks of Barakar formation
are forming bold and rugged and gently southerly dipping topography in east of
the river. The Barakar formation is almost horizontally bedded, weathered and
extensively occupied by the alluvial soil cover ranging from almost 0.5 to 4 m.
Sand is deposited annually during the monsoon, which is mostly derived from
the older rocks exposed in southern parts of the area. Sand of the area doesn’t
allow exploration and mining by the conventional methods, owing to the
unconsolidated nature of the sand dominantly comprising fragments of quarts,
feldspar. Therefore, the anticipated reserves can only be classified in
Recognized Resources Category.
The proposed sand mine in situated at the Hasdo River bed, which originated upstream terrain at Sonhat tehsil. It is the tributary of Mahanadi River. It has medium catchment area. The river bed comprised of unconsolidated alluvial placer deposit of sand and bajari found along the river bed. The rock formations thrusting invasion of Hasdo is within the Barakar formation of the Gondwana Super Group rocks.
Based on the geology consideration thickness of the almost horizontally
deposited sand along the Hasdo River is likely to be over 3 m. The sand (0.1 to
2 mm) deposit is mostly without any waste and overburden material and
mostly common unconsolidated angular to sub-angular and sub-rounded
grains mainly of variety of quarts, feldspar and rarely iron oxide minerals, mica
silt (<0.6 mm) grains. Sorted boulders (>25 cm.), Cobbles (6.4 cm to 25.6 cm.)
pebbles (0.4 to 6.4 cm), gravels (0.2 to 0.4 cm) from angular to sub rounded
makes essential part of the alluvial deposits, but at the surface generally sand
and sorted bajari (gravels & pebbles) are seen.
Local Geology:
The river bed comprised of unconsolidated alluvial placer deposit of sand and
bajari found along the river bed. The rock formations thrusting invasion of
Hasdo is within the Barakar formation of the Gondwana Super Group. Rocks of
Barakar formation are farming bold and nugged and gently westward dipping
topography in eastern part of the river. The Barakar formation is almost
horizontally bedded without significant exposures. The formation around the
area are weathered and extensively occupied by the alluvial soil cover noggin
from almost 2 m. to 10 m.

Annual Replenishment of Sand in the Lease Area:
As per the Ministry and Environment and Forest OM No. J-13012/12/2013-IA-
1I (I) dated 24.12.2013, the annual replenishment of the sand in the lease area
should be sufficient to sustain the mining operation at level prescribed in the
Mine plan.
The replenishment of sand depends mainly upon the catchment area of the
river, annual rainfall in the catchment area erosion of rocks in the catchment
area etc. The proposed area falls under the river bed of Hasdo River.
As stated earlier, the proposed area for sand mining falls under the river bed of
River Hasdo. It has a large catchment area. The average rain fall of the
catchment area of the river varies from 4000-5000 mm. All these factors
indicate that the annual sediments replenishment capacity of the Hasdo is
good enough to sustain the proposed production.
Anticipated life of the mine:
As per the Chhattisgarh Minor Mineral Rules, 2015 There is no provision in the
Chhattisgarh Gaun Khanij Ret Ka Utkhanan Evm Vavsaya Viniyaman Nirdesh
2006 and said rules regarding grant of lease for a fixed period as in case of
other mineral minerals.
As the quantity of sand that will be mined every year will get replenished every
year during monsoon, the sand reserve will not get depleted.
4. DEVELOPMENT AND PRODUCTION PROGRAMME
Development:
The mine is a very small mine and does not require much development work.
Only a ramp of mild gradient of 1 in 15 to 20m will be constructed from
approach road at the river bank to approach the mine.
The excavation of sand will be strictly carried out as per the restrictions
imposed by Chhattisgarh Minor Mineral Rules 2015, Chhattisgarh Gond Khanij
Ret Ka Utkhanan and Vavsaya Viniyaman Nirdesh 2006 and the additional
conditions imposed by Govt. of Chhattisgarh vide Gazette notification dated
1.11.2013 and as the Ministry and Environment and Forest OM No. J-
13012/12/2013-IA-1I (I) dated 24.12.2013.
The Government of Chhattisgarh has imposed the following restrictions on
river bed sand mining vide Gazette notification dated 1.11.2013:
9
1. Mining shall not be carried out within 100 m of any bridge/ National
Highway/ State highway.
2. Mining shall not be carried out within 50 m of any natural water
recourse, dam etc
3. Mining shall not be carried out within 3.0 from the banks of the river
4. Mining shall be carried out up to maximum 3.0 m depth or bed rock in
the river
The Ministry and Environment and Forest OM No. J-13012/12/2013-IA-1I
(I) dated 24.12.2013 imposed the following restrictions on river bed mining.
1. The mining activity shall be done manually. 2. The depth of mining shall be restricted to 3m/water level, whichever is less.
3. For carrying out mining in proximity to any bridge and/or embankment,
appropriate safety zone shall be worked out on case to case basis to the
satisfaction of SEAC/SEIAA, taking into account the structural
parameters, location aspects, flow rate etc. and no mining shall be
carried out in the safety zone so worked out.
4. No in stream mining shall be allowed 5. In case of transportation by road, the transport vehicles will be covered
with taurpoline to minimize dust/sand particle emissions.
Production Programme: As stated earlier, the sand deposition in the area is not of uniform thickness,
the thickness of the sand bed varies from 3.0 m to 3.5 m. The water level in the
proposed mining area goes up to 3.0- 4.0 m below the general sand level in the
area during summer. It is proposed to skim the sand leaving a 2.0 m thick
layer on river bed. To protect the in stream micro and macro flora, excavation
will be restricted above water level which will not affect the turbidity of the
water. In order to protect the natural permeability and porosity of the filter
material due to compaction of filter zone of river bed, no heavy vehicles and
machine will be used.
Skimming will be done manually in layers of 0.5 to 1.0 m. The loading of the
sand will be done manually on tippers/ tractors. A ramp will be constructed
and will be maintained to connect the approach road to the mining area.
Year Proposed Production of sand, m3/year
1st year 60000 m3/year
2nd year 60000 m3/year
3rd year 60000 m3/year
4th year 60000 m3/year
5th year 60000 m3/year

Transportation Infrastructure:
The sand is generally transported by the consumer in their own tractors,
tippers/dumpers. The capacity of the dumpers generally used is 10 m3. The
mining of sand is mostly carried out in 8 months from November to June. The
mining will be carried out only during the day time i. e. from 8 am to 6.0 pm.
The estimation of average requirement of dumper trips per day and per hour is
given below:
Details
Sand Production/year 60,000m3
No of working days in a year 8X30 240 days
Av. Sand Production/day 60,000/240 250.00 m3
Carrying capacity of dumper 10 m3
Av number of trips required/day
250/10 25
No of working hours/ day 10 hrs
Average no of trips/hour 25/10 2.5 or 3
The mine is well connected to village road via a 500m long Kachcha road. The
village Telimuda, Gram Panchayat Kailashpur is connected to NH–78 at about
12 km long Tar road and also by SH at about 2 km. A ramp of gradient 1-15 is
proposed to be constructed for evacuation of sand from the mine. The carrying
capacity of the road is sufficient to take this insignificant traffic of tippers. Also
the requirement of dumpers for transportation of sand is too less only average
3 trips/hour, there will be no queuing of dumpers and no large parking space
will be required.
Man Power Deployment: The average daily employment is tabulated below:
1 Supervisor Skilled 02
2 Loaders Unskilled 20 (considering an OMS of avg 12 m3) 250m3/12m3=20.83
Total 22
Use of Mineral:
Sand is a very important mineral for our society due to its many uses. It can be
used for making concrete, filling roads, building sites, brick-making, making
glass, sandpapers, etc. The sand mined from the mine will be mainly used in
construction industry as a fine aggregate.

5. RECLAMATION PLAN
The proposed mine is of river bed sand mining and only involves scrapping of
thin layers of sand from the river bed. No pits are proposed to be dug that
need backfilling. Also there will no change in the post mining land pattern.
Plantation is not possible within the lease area as the mine is in the river bed.
However, It is proposed to do some plantation of local species of trees along
the approach road and along the river banks where ever possible.
6. STRATEGY FOR PROTECTION OF RIVER COURSE, NALAS, WATER
TANK, VILLAGES, IMPORTATNT MONUMENTS IF ANY
The sand mining is proposed in the river bed of Hasdo River. There is no Nalla, water tank, village, important monuments in the close vicinity of the mine which may get affected due to mining activity. The river bed sand mining can cause the following environmental hazards:
• Instream habitat: The impact of mining may result in increase in river gradient, suspended load, sediment transport, sediment deposition, turbidity, change in temperature, etc. Excessive sediment deposition for replenishment/ refilling of the pits affect turbidity, prevent the penetration of the light required for photo synthesis of micro and macro flora which in turn reduces food availability for aquatic fauna. Increase in river gradient may cause excessive erosion causing adverse effect on the in stream habitats.
• Riparian habitat: This includes vegetative cover on and adjacent to the river banks, which controls erosion, provide nutrient inputs into the stream and prevents intrusion of pollutant in the stream through runoff. Bank erosion and change of morphology of the river can destroy the riparian vegetative cover.
• Degradation of Land: Mining pits are responsible for river channel shifting as well as degradation of land, causing loss of properties and degradation of landscape.
• Lowering of groundwater table in the floodplain area: Mining may cause lowering of riverbed level as well as river water level resulting in lowering of groundwater table due to excessive extraction and draining out of groundwater from the adjacent areas. This may cause shortage of water for the vegetation and human settlements in the vicinity.
• Depletion of groundwater: Excessive pumping out of groundwater during sand mining especially in abandoned channels generally result in depletion of groundwater resources causing severe scarcity and affecting irrigation and potable water availability. In extreme cases it may also result in creation of ground fissures and land subsidence in adjacent areas.
