摘　　要：金山店铁矿余华寺矿区为了解决尾矿堆置问题,拟利用地表塌陷坑进行尾矿干堆排放。为了保证安全生产,利用相似模拟试验的方法,模拟尾矿干堆过程中-340^-410m深部矿体分别使用无底柱分段崩落法与上向进路充填法开采,并监测开采过程中造成的地表沉降、尾矿渗漏、井下应变的情况。试验结果表明,地表塌陷坑尾矿干堆后所监测项目均未出现异常,两种采矿方法均可用于安全生产,上向进路充填法安全性更高。In order to solve the problems of tailings pile,surface collapse pit was used for dry tailings disposal in Yuhuasi mine area of Jinshandian Iron Mine.To ensure production safety during the dry tailings disposal,similar simulation experiments were carried out to simulated deep mining of-340^-410 morebody respectively under non-pillar sublevel caving method and upward drift stoping with backfilling method.And the conditions of surface settlement,tailings leakage and underground strain in the mining process were monitored.The experiment results showed that the monitored projects were not abnormal after dry tailings disposal in surface collapse pit.Two types of mining method were both feasible for safe production,while upward drift stoping with backfilling method had a higher security.
