| 摘 要： | 从片帮型冲击矿压发生的机理出发，分析了煤层煤巷采用锚杆支护减冲的机理。采用锚杆支护，能够增强围岩的自承能力，减缓上覆煤岩层的活动，相对增加了使煤体内裂纹扩展和层裂板结构失稳破坏所需的临界载荷。

| Abstract: | Based on the occurring mechanism of slough rock burst, the mechanism to weaken shock with bolt support in coal roadway is analyzed. Bolt support can improve self-bearing capacity of the surrounding rock,alleviate the activity of rock mass in upper coal, and can increase relatively the critical loading of inner cracks extension and instability with layer-crack-plate construction in coal mass. |
