复杂地质条件下清水营煤矿井巷支护方式

On the Roadway Support Methods in Qingshuiying Coal Mine under Complex Geological Condition

清水营煤矿属于"三软"(顶板软、底板软、煤层软)煤层开采,软岩巷道支护问题严重制约矿井安全生产,加剧了采掘接续紧张。结合地质资料及现场实际情况,提出了切实可靠的支护方案,有效提高了巷道稳定性,增加了巷道施工安全性,对软岩条件下煤矿安全开采具有重要意义。

Coal seam mining in Qingshui coal mine belongs to the ＂three soft＂（soft roof, floor and coal seam）, the problem of soft rock tunnel supporting seriously impeded mine safety production, intensified mining in tension. Combined with geological data and the actual situation, this paper put forward the practical and reliable support scheme, effectively improved the stability of roadway, and increased the safety of tunnel construction, which has great significance for coal mine safety mining under the condition of the soft rock.
