摘　　要：近年来 ,江川清水沟磷矿随开采台阶的不断下延 ,采空区面积将逐年增大 ,每年均发生采空区底板边坡下滑 ,直接影响矿山生产的顺利进行 ,且造成大量水土流失。根据矿区地质并通过现场分析研究 ,得出影响边坡下滑的几种因素 ,并有的放矢地在东、北两矿段采空区采取了防治措施 ,取得了较好效果 ,可供同类矿山作参考。In revent years,the mined-out area of Qingshuigou P deposit has been continuously enlargin because of the mining stage going down.And the sole side slope of mined-out area slipps down every year,which has directyt influenced the mining production and resulted in a great amount of soil erosion.According to the ore field geology and the analysis on spot,several factors causing these slipping have been discovered.And some prevention measures have been used in both the east and west mining areas,which have got good resaults.
