摘　　要：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。The engineering background of the current application is the mechanism of Datong mining area coal bumps caused by mining effect under the condition of hard coal-rock structure. By analyzing the characteristics of rock roof and the bump proneness of dangerous coal seams, the hazard mode of the coal mass instability and integral slip of coal seam induced by mining effect are discussed. Through analyzing behavior characteristics of the mining stress of typical mines, the hazard mode of coal bumps in Datong mining area is clarified, and it can provide support for following hazard control.
