ENVIRONMENTAL IMPACT ASSESSMENT OF POTENTIAL MINING CONCERNS AT THAR COAL FIELDS AND THEIR REMEDIES
The research covers the Tharparkar district is situated in the south east of Sindh province of Pakistan. This research identifies the impacts of ongoing coal mining activity on ground water quality of Thar coal mines area and propose mitigation measures for management of the excessive water from continuous dewatering at mining area. On the basis of different EIA studies anthropogenic impacts on ground water quality of the Thar Coal mining area is determined. Removal of massive quantities of overburden will most likely alter the mass balance at the mining site and hence the sand, and overburden as well water from dewatering of aquifers must be retained within the ecosystem of the Coalfields. Ground water abstraction of about 25 million m3/year will yield abundant volume of brackish water, which will have to be desalinized for cooling purposes of the power plant and for the other beneficial use. Assessment of environmental impact shows that the overall significance of impact is of medium intensity, while the severity of impact is quite significant. Suggestions are proposed on the premise of the present investigation for the administration of Sindh and other partners. The dewatering surplus can straightforwardly be utilized as a part of the power era process as being drilled in different areas of the world. The dewatering surplus can be utilized in growing of the halophytes. The dewatering surplus can be treated with public private partnership to serve the water needs of the Thar District people, flora and fauna.
