摘要
根据祁东煤矿7131工作面开采地质条件及水文地质情况,制定了预防工作面压架突水灾害的技术方案。结果表明:深孔预裂爆破关键层技术是解决松散含水层条件下覆岩整体破断导致灾害的重要途径,ZY10000/23.5/42液压支架能够满足开采条件要求。
According to mining geological and hydrogeological conditions in 7131 working face of Qidong Mine, the article develops technical programs to prevent support break - off and water inrush. The results show that the technology of deep - hole pre - splitting blasting key stratum can solve over burden broken disasters under loose aquifer, and ZY10000/23.5/42 hydraulic support meets the re- quirements of mining conditions.
