摘　　要：基于平顶山十矿复合顶板沿空煤层巷道的变形破坏特点,分析了小煤柱条件下该矿沿空巷道围岩的三角块结构及其失稳破坏形式,得到回采期间该巷道的破坏主要是由三角块结构转动失稳所致,由此提出了沿空巷道锚网索耦合支护技术。Based on the characteristics of deformatinn nf road remained for next sublevel with compound roof in No.10 mine of Pingdings- han,the paper analyses triangle block structure of surrounding rock in road remained for next sublevel with small coal pillar in the mine and form of destabilizing,the analysis result indicates that the destroy of the roadway during extraction period is caused by the destabilizing of triangle block structure,thus net,bolting and cord coupling supporting technology is risen.
