| 摘 要： | 为优化72911工作面巷道支护,以锚杆支护理论为基础,结合掘进期间现场实测结果,获得72911工作面巷帮破坏深度、顶板破坏高度、巷帮载荷集度和顶板载荷集度,确定采用顶板“锚杆+锚索+钢带+金属网”、两帮“锚杆+金属网”的支护形式。监测分析发现巷道表面变形速率降低,巷道变形趋于稳定。

| Abstract: | In order to optimize the roadway support of the 72911 working face,based on the theory of bolt support,combined with the field measurement results during excavation,the roadway side failure depth,roof failure height,roadway side load concentration and roof load concentration of the 72911 working face are obtained.The support forms of roof"bolt+anchor cable+steel belt+metal mesh"and two sides"bolt+metal mesh"are determined.Through the monitoring and analysis of the roadway,it is found that the deformation rate of the roadway surface decreases and the roadway deformation tends to be stable. |
