Due to underground mining of a mine,the ground surface subsides,geological hazards are severe and safe production is jeopardized.A series of analyses were carried out based on survey,using field measurement in subsidence area,stability analysis of subsidence area,tailings paste filling body development,subzone ecological restoration,and finally reached the comprehensive treatment plan of tailings paste filling and earthing vegetation.The plan not only solves subsidence area treatment and tailings stockpiling,but also reclaims an ecologically friendly environment for mines.Besides,it can provide reference for ecological restoration,subsidence area treatment and solid waste utilization for similar mines.
