Utilization of Coal Mine Water

Abstract:

China is a big country of coal production, in the coal mining process, the great massive mine drainage has caused not only the waste of groundwater resource, but also environmental pollution. On the other hand, mining production and life supply water is very scarce. According to the mine water features, the majority of mine drainage water belonging to the mine water containing suspended, the mine water needs to do the necessary purification then can be used. What the purification mainly eliminates is the suspended. In this paper, the method of purification and the technological process about mine water are discussed. The main methods of handling are coagulation, sedimentation, filtration and disinfection. According to different characteristics of water quality, different ways of handling and technological processes have to be chosen. Finally, the purification and utilization of mine water are shown through practical examples, Pingdingshan Coal Group Company, Wannian Coal Mine of Fengfeng Group Limited Company and Tangshan Coal Mine of Kailuan Group Company, to have obvious social, economic and environmental benefits.
