以大同矿区坚硬煤岩组合条件下采动影响区域冲击地压发生机理为背景,分析了矿区冲击危险性煤层的顶板特点和煤层冲击倾向性,探讨了采动应力诱发煤体材料失稳和煤层整体滑移的致灾模式。通过分析典型冲击矿井的开采地质条件和采动效应,明确了大同矿区冲击地压的致灾模式,可为后续有针对性的灾害防治提供参考。
Based on the mechanism of rockburst in the mining affected area under the condition of hard coal and rock combination in Datong Mining Area, the roof characteristics and coal seam impact tendency of coal seam with impacting danger are analyzed, and the effects of mining stress-induced instability of coal material and coal seam The overall slip of the disaster model. By analyzing the mining geological conditions and mining effect of the typical impact mine, it is clear that the rock burst mode in Datong mine area can provide a reference for the follow-up targeted disaster prevention and control.
