锡矿山南矿采用胶结充填矿壁、尾砂充填矿房的全面充填采矿法回采河床保安矿柱,获得了较好的效果。实践证明,该法不仅技术可行,生产安全,而且经济合理,较好地解决了矿山生产上的重大课题,同时也为类似条件矿体的开采提供了借鉴。本文着重阐述了现场地压观测和研究的某些结果,并且探讨了采用该法控制采场地压和岩层移动的机理及规律。
The South Mine of tin mines adopts the full filling mining method of cemented filling mining wall and tailings filling mineral house to recover the riverbed security pillars and obtains good results. Practice has proved that this method is not only technically feasible and safe in production, but also economical and reasonable, which can well solve the major issues in mine production and provide reference for the exploitation of ore bodies with similar conditions. This paper focuses on some of the results of field ground pressure observation and research, and discusses the mechanism and rule of using this method to control stratum pressure and strata movement.
