An Approach to Some Questions in Water Supply and Drainage Design for Coal Mines

The current situation of water supply and drainage in coal mines and existing problems are analyzed.Problems existing in the design of water supply and drainage for coal mines as well as the way forward for improvement are studied in the aspects of selection of water supply sources,water supply in mines,treatment of circulating cooling water for mining industrial sites and of wastewater from coal mines, etc.Discussions are made on rational utilization of the effluent water resources in mines and rational disposition of water supply and drainage systems and circulating water systems,with a conclusion made that feasible solutions for the treatment of coal mine wastewater must be selected in combination with practice.
