摘　　要：针对急倾斜特厚煤层水平分段综放工作面回采巷道频繁出现强烈矿压显现和动力灾害造成巷道瞬间变形破坏现象,通过现场测试和理论分析研究动力灾害发生机理,采取综合防治措施,很好地解决了动力灾害问题,促进了矿井安全生产。Frequent and violent underground pressure behavior and dynamic disaster made roadways deform and damage instantaneously in full-mechanized caving mining face with horizontal sections in steeply inclined and extremely thick coal seam. Mechanism of dynamic disaster was analyzed by scene test and theoretic research in this paper. Integrated prevention measures were adopted to prevent dynamic disaster and ensure safety.
