II-5-Ground Water Management in Jhamarkotra Mines.

Abstract

Mining by its nature is an activity where progress is made by adopting safe, economic and environment friendly path. This is possible only by understanding different natural phenomenon operating in and around the mining area. These phenomenons can be related either to stresses existing in the earth's crust or to behaviour of ground water regime. Mining operations planned and implemented on the basis of such studies make them safe, economic and environment friendly so that they benefit the mankind and posterity. Jhamarkotra mine known for Phosphate mining is located 26 km southwest of Udaipur city in Aravali hills is made up of meta-sedimentary rocks. Mining activities in Jhamarkotra mine is facing problem due to presence of groundwater in phosphate bearing dolomitic limestone rock. In the present study, source and flow path of groundwater has been identified using multidisciplinary approach using hydrogeological investigations, remote sensing techniques, isotopic studies, and resistivity survey. To control groundwater in mining area, sites for new tube wells are suggested to withdraw groundwater and to lower the water level in mine area.
