摘要
以山西某煤矿为背景,运用岩土工程力学分析软件FLAC3D,对旧式房柱式采空区围岩的应力场及破坏特征进行了分析,并在此基础上确定了底板巷道布置的最优位置。有针对性地提出了底板巷道的支护方案,并对支护效果进行了监测,监测结果表明巷道布置较为合理,支护方案可有效控制围岩变形。
Taking a coal mine in Shanxi Province as background, using geotechnical engineering mechanical analysis calculation soft- ware FLAC3D , we had analyzed the stress field and the failure eharaeteristies of the surrounding rock in room and pillar gob, and on this basis, we determined the reasonable layout for floor roadway. Then, we proposed the roadway support scheme and monitored the supporting effect. The results show that the floor roadway deformation is under control and the roadway support scheme is effective.
