摘　　要：为防止富家凹煤矿11205孤岛工作面运输巷受到邻近11207工作面采空区上覆顶板下沉的动压影响,在进行巷道顶板窥视和现场调研基础上,依据动压影响和围岩松动范围,对巷道采用“分段支护方案+高强预应力全锚索支护”技术。现场施工和后期矿压观测结果表明:该技术方案保证了巷道的稳定和采掘接替。In order to prevent the transportation roadway of the 11205 isolated island working face in Fujia'ao Coal Mine from being affected by the dynamic pressure caused by the subsidence of the goaf overlying roof near the 11207 working face,based on the observation of the roadway roof and on-site investigation,and according to the influence of dynamic pressure and the range of surrounding rock loosening,the "segmented support scheme+high strength prestressed full anchor cable support" technology is adopted for the roadway.The on-site construction and post mining pressure observation results indicate that this technical scheme ensures the stability of the roadway and the replacement of mining and excavation.
