摘　　要：为解决桑树坪煤矿11号煤带压开采底板隔水层厚度不足问题,研究了以奥陶系灰岩顶部为工作层的防治水技术方法。分析了3105工作面带压开采的条件,论证了奥陶系灰岩顶部工作层的必要性,研究了奥陶系灰岩顶部的隔水性能,确定了工作层在奥陶系灰岩中的深度,给出了工作层内奥陶系灰岩的探查治理方法,总结了3105工作面所实施的各项防治水工程。实践证明,以奥陶系灰岩顶部为工作层开展防治水后,工作面可安全回采。To solve the issue of watertight stratum thickness insufficient during the mining under safe aquifer water pressure of coal No.11 in the Sangshuping coalmine,put forward a water control means regarding the Ordovician limestone top as a working layer.Thus analyzed working face No.3105 mining under safe water pressure of aquifer condition,demonstrated the necessity of regarding Ordovician limestone top as a working layer.Then studied the watertight performance of Ordovician limestone top,determined the depth of working layer in Ordovician limestone,given out Ordovician limestone exploration and governing means within working layer,summarized working face No.3105 implemented various water control engineering.The practices have proved that water control regarding Ordovician limestone top as working layer,so that working face can be safely extracted.
