义能煤矿3^#煤层冲击危险性评价与防治

Risk Assessment and Prevention of Rock Burst in No.3 Coal Seam of Yineng Coal Mine

针对山东义能煤矿周边矿区冲击地压频发工程特性,为使义能煤矿3^#煤层冲击危险性评价更具有直观性与便捷性,综合考虑义能煤矿地质因素、生产管理与实际情况,利用理论分析将各项影响因素赋值后使用综合指数法对义能煤矿冲击危险性进行评价,得出义能煤矿3^#煤冲击可能性指数为0.818,可能性等级为"很可能",并基于此制定对齐停采线、防冲措施。

According to the engineering characteristics of frequent occurrence of rock burst in the surrounding mining areas of Yineng Coal Mine, in order to make the risk assessment of No.3 Coal Seam in Yineng Coal Mine more intuitive and convenient, the geological factors, production management and actual situation of Yineng Coal Mine were comprehensively considered, and the impact factors were assigned by theoretical analysis, and the comprehensive index method was used to evaluate the rock burst risk of Yineng Coal Mine. The result shows that the impact probability index of No.3 Coal in Yineng coal mine is 0.818, and the possibility level is "very likely". Based on this, the measures for aligning the stoppage line and preventing erosion are formulated.
