摘要:
摘 要: 宽沟煤矿处于我国西北强地震区域,地质和地球物理特征以及岩体结构复杂。利用钻孔光学窥视装置及系统,探测了E1142轨道平巷顶板岩层动态破裂特征,统计分析了裂隙分布规律。结果表明:顶板岩体裂隙以纵向裂隙分布为主,主要集中在顶板浅部,在巷道肩窝处的裂隙较为集中,这对巷道的控制与加固具有指导意义。
Abstract:
Kuangou Coal Mine is located in a strong earthquake region of northwest of China. It is of complex geological and geophysical environment and rock structure. The strata dynamic cracking characteristics of E1142 haulageway in fractured roof were investigated by optical peephole device. Through the statistics of cracks and distributing characteristics, it is found that roof of the broken rock fissures/cracks appeared on the main vertical fissure, and cracks were mainly distributed in the shallow broken roof. The fracture was more centralized in irregular laneway of roof. Therefore, the different supporting design should be applied according to the different rock structure to achieve the good supporting effect. The results of the laneway to maintain stability is of great significance.
