摘要
深部巷道支护成为目前制约煤矿深部开采的重要因素之一,进行众多复杂的措施来多次维护深部巷道流变围岩虽已取得一定效果,但有效控制深部破碎、软弱、流变围岩大变形仍非常困难。通过分析导致变形、破坏、失稳的各种原因,提出对于破碎难维护围岩,在加强帮顶控制的同时,应对底板采取加固处理。研究结果表明将顶、底、帮围岩作为整体进行治理,完全能够实现控制围岩大变形的目的。
the deep roadway supporting has been one of the deep mining problems,and took many maintenance measures to control the flow surrounding rock,but it always was the difficult to gain the successful effect of controlling deep breaking,soft and flow deformation rock. In this paper,that the reinforcing floor meanwhile supporting rib and roof was put foreword by analyzing the all kinds reasons of leading to deformation,damaging and losing stability. The result showed that the controlling of large deformation surrounding rock was effective by take roof,floor and rib as a whole to control,especially reinforcing the floor by bolting and injecting.
