煤矿开采导致水污染的污染特征与控制措施研究

Study on Pollution Characteristics and Control Measures of Water Pollution Caused by Coal Mining

煤矿开采导致地下水资源严重污染,深入研究煤矿开采致水污染的污染特征与控制措施,分析煤矿开采中煤矸石排放和矿井排水对地下水污染影响,以及煤矿闭坑对地下水运动和地下水水质的影响,获取煤矿开采致水污染的特征,包括煤矸石山水淋滤的渗污染型、井巷串水污染类型、第四系水因顶托补给污染类型和地表水涌入污染类型,在此基础上研究助凝剂和混凝剂用于处理矿井水污染物工艺,实现对矿井污染水的有效净化。

The groundwater resources are seriously polluted by coalmining.The pollution characteristics and control measures of water pollution caused by coal mining are studied in depth.The influence of coal gangue discharge and mine drainage on groundwater pollution in coal mining is analyzed.The influence of coalmine closure on groundwater movement and groundwater quality is also analyzed.The characteristics of water pollution caused by coal mining are obtained,including the seepage pollution type of coal gangue hill water leaching.On the basis of this,coagulant and coagulant are studied to deal with mine water pollutants and realize the effective purification of mine polluted water.Enterprises can realize coal mining by developing new coal mining technology,strengthening the supervision of coal enterprises and mine management.
