摘要
基于阳煤寺家庄矿现有的支护模式,分析了该矿采用高强度锚索支护后顶板的下沉情况,研究结果表明,当对原有的支护技术进行加固后,能够有效控制目标工作面的巷道变形情况。
Based on the existing support model of Sijiazhuang Coal Mine in Yangmei City,the subsidence of roof supported by high strength anchor rope is analyzed. The results show that the original supporting technology can effectively control the roadway deformation of the target working face after reinforcement.
