【摘要】 煤矿冲击地压一直是岩体力学及矿山压力防治研究的难点之一,从理论到防治都尚未完全解决。随着矿井开采深度的增加,发生冲击地压的矿井越来越多,强度也越来越大,造成巨大的经济损失和人员伤亡,给安全生产带来巨大压力。冲击地压已成为威胁煤矿安全生产的严重自然灾害之一。本文以新汶孙村矿为研究对象,通过地质动力区划方法确定区域地质构造背景,建立地质构造模型; 采用理论分析、数值计算等综合研究方法确定孙村块区区域内的各级活动断裂,划分岩体断块结果; 通过井下地应力测量和数值模拟方法确定岩体应力状态; 采用多因素概率预测方法完成冲击危险性的区域预测,进而划分出发生冲击地压的危险区、威胁区与安全区,对冲击地压危险性做出评估和预测。对孙村矿今后冲击地压预测、检测和综合防治工作起到了指导作用。更多还原

【Abstract】 The rock burst in coalmines is always one of the difficult problems on rock mass mechanics and mine pressure, which is not solved in the theory and in practice. Along with the increasing of the coalmine depth, the coalmine which has impacted rock burst more and more, and the intensity was also more and more big, all that have created the huge economic loss and the personnel casualty, this phenomenon has caused the huge pressure for the safety in production, so rock burst has become one of serious disasters in safety production of coalmines. The Suncun coalmine is regarded as the research object in this thesis, in this paper the method of geo-dynamic division was used to determine the regional geologic structure background, and then established the geologic structure model; synthetic study method such as theoretical analysis, numerical computation were used to divide the active fault of all levels in the region of Suncun coalmine, and through that methods to divide the stress state block fault; State stress measurement and numerical simulation method were used to determine state stress condition; Used the multi-factors probability prediction method to complete the regional prediction of rock burst, then divided the danger area, the threaten area and the safety area, and made the appraisal and the prediction of rock burst risk, and given a instruction to Suncun coalmine for the regional prediction, the examination and the preventing and controlling of rock burst.更多还原
