摘要
以晋北煤业5-103工作面为研究对象,针对工作面过空巷时巷道围岩变形严重的问题进行了理论分析,并研究了过空巷充填技术的应用,得到高水充填后巷道顶板的最大位移量为141 mm,两帮的最大位移量为94 mm。该技术的应用为安全高效生产提供了重要保障。
Taking the 5-103 working face of Jinbei Coal Industry Company as the research object,this paper carried out theoretical analysis of the problem of serious deformation of the roadway surrounding rock when the working face crossed the empty roadway,and studied the application of the filling technology for crossing empty roadway.It was obtained that the maximum displacement of the roof was 141 mm,and the maximum displacement of the two sides was 94 mm after high water filling.The application of the technlolgy can provide important guarantee for safe and efficient production.
