摘要
通过对潘一煤矿西二采区缩小防水煤柱块段13-1煤底分层赋存条件及其顶板岩性特征的研究,顶分层覆岩破坏规律的分析与研究,上覆松散含水层及基岩风化带的划分与评价,以及顶分层试采工作面出水及压架原因分析与研究,论证了本底分层块段缩小防水煤柱上综采的可行性。
By studying on the occurrence condition and roof rock feature of No. 13 - 1 sublayer coal of the reducing waterproof coal pillars in No. 2 west mining area of Panyi Coal Mine, analyzing the overburden failure law of top slice, classifying and evaluating the overlying unconsolidated aquifers and weathering zone of base rock, and researching on the reason of water output from the working face of top slice as well as the cause of pressing bracket, we demonstrated the feasibility of fully mechanized coal mining on this sublayer coal of the reducing waterproof coal pillars.
