介绍了新峪煤矿近距离煤层开采巷道顶板的破坏特征,在锚网索支护的条件下顶板出现“网兜”现象并伴随大量的钢带撕裂、锚索断裂和锚杆脱落,靠近巷帮的第2根锚杆或锚索首先破坏,顶板冒顶表现为沿巷帮直切下落等现象。分析了巷道顶板破坏的主要原因为地压不变的条件下围岩强度逐步弱化的结果。最后介绍了近距离煤层采空区下巷道顶板支护设计成功的工程实践。 Described the destruction characteristics of the roadway roof in XinYu coal mine near distance coal seam. Under the condition of anchor net support, the phenomenon of “net pocket ” appears with the tearing of the steel strip, the breaking of the anchor line and the fall of anchor bolt, Alley to help the first two anchor bolts or cables destroyed, the top of the roof performance for the fall along the road to help straight down and so on. The main reason of roadway roof failure is analyzed as a result of gradual weakening of surrounding rock strength under constant ground pressure. Finally, the successful engineering practice of roof support design of mine roadway under the close distance coal mined area is introduced.
