analysis of the hydrogeological data of the experimental

site, the following conclusions were drawn –

the hydrogeological conditions of the experimental site

has changed considerably due to extensive water

pumping resulting in drawdown in aquifer ‘A’ ( saturated

thickness 4 m).

No need of dewatering operation in Aquifer ‘A’

Aquifer ‘B’ below Lignite seam is multilayered thick

system

Advanced dewatering required for Aquifer ‘B’,

The hydraulic conductivity and storavity of Aquifer ‘B’ is

0.0008m/day & 0.002 respectively

Environmental protection measures needed against water

Hydrogeology of Indian Coalfields

CONCLUSIONS

Coal India is the pioneer organization to establish

ground water regime of Indian Coalfields.

Indian Coalfields are normally bounded by

crystalline rocks. The hydraulic conductivity of

crystalline rocks varies from 0.1 to 1.5 m/day and

yield ranges from 42 to 250 m3/day.

The aquifer in Indian Coal bearing formation is

mostly constitutes Gondwana sandstone. The

hydraulic conductivity ranges from 0.5 to 50m/day

and yield ranges from 84 to 1176m3/day


Hydrogeology of Indian Coalfields

CONCLUSIONS

The Indian coal mostly acts as aquitard having

hydraulic conductivity ranging from 0.005 to

0.03 m/day.

In underground mining the estimation of mine

water inflow under caving condition in Wardha

valley, Sohagpur and Ib Valley Coalfields had been

done in selected mines. The mine water inflow

ranges from 550m3/day to 5000m3/day.


Hydrogeology of Indian Coalfields

CONCLUSIONS

In open pit mining the advance dewatering

operation in selected mines of Indian Coalfields

viz. Rajmahal (ECL), Wardha Valley (WCL)

Singrauli (NCL) have been done. The advance

pumping from the respective mines ranges from

5000 to 60000 m3/day.

The problem related to environmental impact

likely to be caused by ground water pumping during

active mining is being addressed.


Hydrogeology of Indian Coalfields

CONCLUSIONS

To identify the problem of depletion of ground

water due to mining , hydrographic monitoring

stations has been established in Indian Coalfields

and monitoring of water levels , four times in a

year viz January, May, August and November is

being done as per guidelines of Ministry of

Environment and Forest (MoEF) Govt. of India

Problem of ground water depletion, once

identified the remedial measure is undertaken to

augument water level by implementing artificial

recharge system such as Rain water harvesting,

Creation of water lagoon in mined out region and

recharge through abandoned tube wells.


Hydrogeology of Indian Coalfields

CONCLUSIONS

All efforts are being made to restore original

water table by land reclaimation and sand stowing

after the closure of open pit and underground

mine respectively to accelerate recharge of

ground water system of the area.
