红层地区煤矿地表水害防治研究与实例分析

Research on Coal Mine Surface Water Disaster Prevention and Case Analysis of Red Rock Area

红层岩土体中含有可溶成份,在水的作用下容易发生岩溶、渗流等,为地表水体进入煤矿的良好通道。铁箕山煤矿2次淹井事故的渗透通道都是红层溶洞,对其进行了研究分析,并通过河床改道消除隐患。

The red layer of rock etc., and is a good channel accident penetration channel in and soil contains soluble ingredients prone to karst and seepage, for surface water into the coal mines. Two times flooded well Tiejishan Coal Mine are all red layer caverns, by research and analysis, the river bed diversions can eliminate the hidden dangers.
