辽宁金凤井下采空区充填密闭与脱排水技术及应用

Technology and Application of Tailings Filling, Sealing and Dewatering in the Goaf of Jinfeng Gold Mine, Liaoning Province

针对辽宁金凤金矿面临的遗留采空区地压显现问题,采用超细粒全尾砂似膏体充填工艺进行地压管理,介绍在实践过程中采用井下采空区充填密闭和脱排水技术,为其它类似矿山的推广应用提供经验参考。

This paper was aimed at the problem of ground pressure manifestation in the left-out goaf faced by Jinfeng Gold Mine in Liaoning, this paper adopted the ultra-fine-grained full tailings-like paste filling process for ground pressure management, and introduced the filling and sealing of the underground goaf adopted in the practice process. Dewatering technology could be used as a reference for the promotion of other similar mines.
