摘要
为解决破碎顶板大断面巷道施工中的围岩变形问题,结合某煤矿井田破碎顶板大断面巷道实际情况,在介绍原巷道支护方式、围岩变形破坏特征及产生原因的基础上,提出优化联合支护技术,以期为相关人员提供参考。
In order to solve the problem of surrounding rock deformation in the construction of large section roadway with broken roof slab,combined with the actual situation of large section roadway with broken roof slab in a coal mine field,on the basis of introducing the original roadway support method,surrounding rock deformation damage characteristics and causes,the optimized joint support technology is proposed,in order to provide reference for relevant personnel.
