依据刘东煤矿的煤层地质及生产技术条件,采用数值模拟分析和现场实测的方法,研究了极近距离煤层联合开采时采场覆岩活动特征和矿压显现规律。研究结果表明,极近距离煤层联合开采上覆已破断岩层可再次形成稳定结构,在端头区覆岩结构的形成有利于集中运输巷道的维护;下位煤层工作面矿压显现缓和,支架承受静载荷作用明显,工作面来压和支架载荷具有整体一致性的特征。 According to coal seam geology and technical conditions of production in Liudong Coal Mine, the characteristics of overburden strata movement and the law of occurrence of strata pressure were studied by means of numerical simulation and field measurement. The results show that the formation of overlying strata in the tip zone can facilitate the maintenance of concentrated transport tunnels. The strata pressure of working face of lower coal seam appears to be relaxed, Load effect is obvious, the face to pressure and stent load with the overall consistency of the features.
