Abstract
Coal mining not only produces a large amount of mine water but also may cause water pollution. Therefore, economic treatment and efficient reuse of mine water are the main research directions of the mine area at present, and the realization of optimal dispatching and efficient reuse of mine water is an urgent problem to be solved. Based on the Na Lin mining area as an example, based on maximizing the reuse rate of mine water, summarizes the mine water level fractionation utilization pathway and classification of mine water dispatching mode, build the Na Lin mining area water supply dispatching model, analyzed the Na Lin River No. 2 mining area water supply dispatching model and the space-time change of water dispatching, through comparing with traditional dispatching model, the results showed that: The constructed water dispatching model can significantly improve the mine water recycling rate in Na Lin river mine area, which provides a certain theoretical basis for the study of efficient utilization of mine water.
