摘要
In the present invention there is provided a process for making and artificial aquifer over a mining subsided and degraded land, which comprises in combination a plurality of stratified overlying layers of varying thickness of fly-ash, clay, fly-ash, green mulch, mine waste rocks, green mulch, mine waste rocks, green mulch, fly-ash and green mulch, respectively, in a mining damaged land-trough. The stratified aquifer will be able to hold water to make it available to the plants grown on it for revegetation of the mining areas especially during hot summer and at the same time it will not allow much areas especially during hot summer and at the same time it will not allow much of the water to percolate below ground to increase water seepage in underground mines. This process will further act in utilization of mining waste and fly-ash which is an eco-hazard. The underground mines will be benefited by use of less number of high capacity pumping cost. Post monsoon the aquifer will be able to retain water for a much longer duration, which may extend upto several months, than the disturbed soil can accumulate without the aquifer.
