| 摘 要： | 为了研究覆岩结构对冲击矿压的影响,以关键层理论为基础对某煤矿上覆岩层结构进行了划分,并利用微震监测技术对巨厚上覆岩层破断规律进行了分析,研究结果认为对上覆岩层可根据岩性、厚度不同划分成不同级别的关键层结构,这些结构初次破断形成的"O-X"型破断结构有主亚之分.大尺度的覆岩结构在破断过程中释放巨大能量形成矿震,是冲击矿压...

| Abstract: | Based on the key stratum theory,overlying strata structures in one coal mine are divided,and micro-seismic monitoring is used to analyze its rupture regularity.The results show that the overlying strata are divided into key strata of different grades according to lithology and thickness.The initially formed O-X fracture structures have the main O-Xone and the sub-level O-Xone.Large amount of energy is released and mine earthquake takes place during the breaking of large scale overlying strata structures,for... |
