摘要
本文针对辛置煤矿东四延伸采区10#煤层顶板含水层突水危险性及直接含水层(K2灰岩)的主要影响,通过分析顶板破坏特征,采用AHP层次分析法,得出导水裂隙带发育高度,K2灰岩含水层突水危险性分区图,由此可知突水危险区主要位于采区中部,为矿井安全生产提供了指导。
Aiming at the risk of water inrush from the roof aquifer of No.10 seam and the main impact of the direct aquifer(K2 limestone)in Dongsi extension mining area of Xinzhi coal mine,By analyzing the damage characteristics of roof and using AHP analytic hierarchy process,the development height of water diversion fracture zone and the zoning map of water inrush risk of K2 limestone aquifer are obtained.It can be seen that the water inrush risk area is mainly located in the middle of the mining area,it has guided the safety production of the mine.
