摘　　要：随着国民经济的发展,水环境受到了越来越严重的污染,水资源变得日益紧缺,使得水源可持续性成了迫在眉睫的问题。当前煤矿行业工业废水中的矿井水成分复杂,利用少,浪费排放对环境也有危害。矿井水是伴随煤炭开采而产生的地表渗透水、岩溶水、老窑积水、地下含水层疏放水及煤矿生产、防尘用水等组成,通常含有大量的悬浮物,如果不加治理白白排掉,造成水资源浪费的同时还污染水生态环境。文章首先探讨了我国煤矿行业水资源现状,分析了煤矿行业矿井水的几种处理方法特点,详细论述了煤矿行业矿井水的混凝法处理机制,最后进行了实验分析,认为PAC投入20mg/L再配合投入3mg/L PAM絮凝效果最佳。With the development of the national economy, and the water environment by growing pollution of water resources become increasingly scarce water sustainability problem became urgent. Mine water in the coal mining industry in the industrial wastewater but complex composition, the use of less waste of emissions on the environment and hazardous. The paper first examines the situation of water resources of China＇s coal mining industry, coal industry, several mine water treatment method characteristics, discusses in detail the coal mining industry, mine water Coagulation handling mechanism, the experimental analysis that the PAC invested 20mg / L together with invested 3mg / L PAN floeeulation best.
