煤矿分区安全治水措施研究与应用

Research and Application of Safety Water Control Measures in Coal Mine Zoning

针对某煤矿由于富水引发的透水等水患问题,结合煤矿的具体地质情况,深入研究了水患来源与井田水文地质特征间的关系,针对5号煤层进行分区治理,并提出了相应的防治水措施。实践证明:采用分区治理相关措施后,可开采区Ⅰ区域的积水面积减少近77%,积水量减少约85%,煤层底板富水性范围明显减小。可采区域面积增大了10%,给煤矿带来近1000万元的经济效益。

In response to the water seepage and other water hazards caused by abundant water in a certain coal mine,combined with the specific geological conditions of the coal mine,the relationship between the source of water hazards and the hydrogeological characteristics of the mine field was deeply studied.Zonal governance was carried out for the No.5 coal seam,and corresponding water prevention and control measures were proposed.Practice has proven that after adopting measures related to zoning governance,the water accumulation area in Zone I of the exploitable zone has decreased by nearly 77%,the water accumulation amount has decreased by about 85%,and the water richness range of the coal seam floor has significantly decreased.The mining area has increased by 10%,bringing nearly 10 million yuan in economic benefits to the coal mine.
