针对冲击地压矿井巷道支护难的问题 ,根据煤岩体冲击碎胀破坏机理 ,按照锚固约束层作用原理 ,提出了发挥锚固约束层的最佳支护形式 :全长锚固水泥药卷锚杆技术 ,介绍了该锚杆的性能特点及应用情况 ,对冲击地压矿井、软岩矿井与高地压矿井需要高强度高锚固力的巷道支护具有很好的借鉴作用。 According to the mechanism of impact crushing and expansion of coal and rock mass, according to the action principle of anchorage constraint layer, the best support form of anchorage constraint layer is put forward: full-length anchorage cement roll bolt Technology, the performance characteristics and application of the anchor rod are introduced. It is of great reference to the roadway support which requires high strength and high anchorage force in rock burst pit, soft rock mine and high pressure mine.
