摘　　要：以利民煤矿09112综采工作面为研究对象,分析了该埋藏条件下开采9煤层时工作面矿山压力显现特点、顶板破断运动规律、液压支架运行状况及对9煤层顶底板的适应性、两区段巷道超前支承压力显现规律,为后期开采091采区及实现矿井高产、高效、安全、低耗积累了经验。Taking the fully mechanized coal face 09112 in Limin coalmine as an examp le in this paper,then it analyses the characteristic of strata behavior、the law of roof rupture、the working state of hydraulic support and its adaptability to the around terrane of 9 coal、the variational law of abutment pressure in the two roadways while exploiting 9 coal.Finally,The conclusion of this article provides the experience to exploit the other coal faces in 091 mine section and achieve the aim of the High-yield,efficient,safe,low-waste and Balanced production.
