摘　　要：为研究矿震诱发型冲击地压的机理与防治方法,基于覆岩空间结构理论的基本思想,结合矿山压力与力学分析,研究了"不对称孤岛综放工作面"覆岩运动规律,探索了"硬岩断裂型"矿震的预测方法,结合鲍店煤矿103上02工作面的开采实际,准确预测了103上02切眼至103上01切眼工作面轨道巷冲击地压危险区、相邻工作面初次来压阶段、单工作面"见方"阶段、双工作面"见方"阶段、103上02工作面接近103上03终采线5个极易发生动力灾害的危险区以及危险程度,并在危险区内提前进行了卸压处理,在工作面推进过程中发生数十次2.5级以上矿震的情况下,成功避免了井下矿震诱发的冲击地压灾害,保证了103上02孤岛综放工作面的安全开采,实现了"有震无灾"的控制目标。Abstract：To make research on the mechanism and preventative measure of the mine earthquake-induced rock burst, based on the theory of the spatial structure of the overlying strata, by adopting the rock pressure and mechanical analysis, the movement regulation of the overlying rock concerning the fully mechanized caving face of the asymmetric island, and further probes the prediction and evaluation methods of the hard rock-fracture mine earthquake were researched. Combining with the actual exploration of the 103上02 coal face of Baodian Coal Mine,five dangerous areas where dynamic disasters occur easily were predicted, namely, the rock burst dangerous area of the orbit crossheading from the 103上 02 cutting hole to the 103上 01 cutting hole,the initial pressure phase between neighboring coal faces, the phase of the single coal face of the advanced distance that equals to one longwall face length, the double coal faces of the advanced distance that equals to two longwall face lengths, and the stopping exploration line of the 103上03 coal face. Furthermore, the types of dynamic disasters were also predicted. The prediction effectively promotes the pressure relief in dangerous areas in advance. In the case of the occurrence of mine earthquake （ above 2.5 levels） for many times, the pre-processing of the pressure relief successfully avoids the rock burst underground, thus ensuring the secure mining of the 103上02 coal face and then realizing the controlling purpose of eliminating the disaster even if the mine earthquake occurs.
