为有效准确的预测矿煤层冲击地压危险性,采用有限元软件ANSYS对断层处煤层的冲击性进行模拟,分析断层对煤岩应力大小及其分布的影响规律,研究得出:断层对煤岩应力分布有较大影响,即断层附近应力梯度较大,煤岩应力集中位置主要出现在断层与煤层相交处附近;在断层附近的煤层即使无冲击倾向性,煤层也可能存在较强的冲击危险性。研究结果对相似煤层冲击地压的预测有借鉴作用。 In order to predict the rockburst risk effectively and accurately, the finite element software ANSYS was used to simulate the impact of the coal seams on the fault, and the influence of the fault on the stress and its distribution was analyzed. Stress distribution has a greater impact that the stress gradient near the fault larger coal and rock stress concentration occurs mainly in the vicinity of the intersection of the fault and the coal seam in the vicinity of the fault without the tendency of coal seams, the coal seam may also have a strong impact hazard Sex. The results of this study can be used as a reference for the prediction of rock burst under similar conditions.
