WASTE WATER IN MINES AND STATUS OF UTILIZATION

The quality of water in mines at production stage affects the working of mines and surrounding water regime significantly. In many mineral producing countries, the pre-mining prediction of water quality is must for getting lease or licence for mining operations. In this paper, various methodologies for prediction of the water quality in terms of pH, TDS, conductivity and metal concentration at the exploration stages were discussed. Such adverse information before start of mines is not only be useful for planning the water pollution control in advance but also help in mitigation of ill effects on mining on surrounding water regime.
