摘要
为了寻求海孜煤矿745工作面"5.21"重大突水事故的根源,从根本上消除工作面水患威胁,实现安全回采。根据矿区的地质和水文地质条件及查治工程成果,全面深入分析了其突水背景、原因、通道、水源等,得出是由于多煤层采动,整体块状巨厚岩浆岩下煤岩层不均匀沉降,产生了离层水体,在巨厚岩浆岩的动力冲击下,引发突水。针对突水的动力特点,提出了在工作面影响以外的下山方向布置钻孔的探放导水治理技术。实践证明,该治理技术有效地阻止了离层水源的产生,保证了工作面安全生产,且对类似条件下水害防治具有借鉴和指导意义。
In order to search the sources for the "5·21" great mine water inrush accident occurred in No.745 coal mining face of Haizi Mine, to fundamentally eliminate the water disaster threatened to the coal mining face and to have a safety mining operation, base on the geological and hydrogeology conditions and the mine water investigation and control results in the mining area, the paper fully analyzed the water inrush background, cause, channel, water sources and others. The analysis results showed that due to th...
