Study On The Technology Of Full Tailing Cement Filling In Goaf Of Rare Earth Mine

In this paper,Weishan Lake rare earth mine urgently need to address the roof collapse collapse,pillar crushing and other major safety issues to start the study.If the mined-out area collapses in the mined-out area,it will pose a huge threat to the surrounding operations and the ground buildings.In addition,the underground mines are relatively large and adjacent to each other.If the surrounding rock of a mined-out area of an ore body is displaced,Seriously affecting the mining operations around the ore body,but also led to a large number of ore resources can not be timely recovery.According to the actual situation and existing problems of Weishan Lake rare earth mine,Goaf technology to design,based on the experimental study of the whole tailings mining area,from the slurry preparation,filling system technology and filling effect of several aspects of the design test,a fundamental solution to the Weishanhu rare earth mined-out area of deformation,Collapse problem,improve resource utilization,protect the lives and property of residents.
