动压煤巷全锚索支护技术研究与实践

Research and Practice of Full Anchor Cable Support Technology in Dynamic Pressure Coal Roadway

为解决动压煤巷支护技术难题,就阳煤五矿巷道原支护情况以及变形情况,提出了优化支护设计。通过在8210工作面回风巷推广三高一低的全锚索支护技术,根据巷道支护矿压观测情况来看,有效控制了巷道的围岩破碎问题,提升了巷道的支护强度,减少了巷道破坏变形量。

In order to solve the technical problems of dynamic pressure coal roadway support,the original support and deformation of the roadway are introduced,and the optimal support design is put forward.By promoting the three-high-low full-anchor cable support technology in the 8210 working face return air roadway,according to the ore pressure observation of the roadway,the fracture change of the surrounding rock of the roadway is effectively controlled,the supporting strength of the roadway is improved,the deformation of the roadway is reduced and the reference for the support design of the roadway is provided.
