摘要
首云股份有限公司铁矿采用中深孔高分段空场法代替原浅孔留矿法开采急倾斜薄矿体,解决了原采矿效率低、安全性低以及与下盘平行厚大矿体回采中段下降不平衡等问题。实践验证了中深孔高分段空场法开采急倾斜薄矿体的可行性。
Adopt medium-deep hole high sublevel stoping method instead of short hole shrinkage method mining steeply-inclined thin orebody in shouyun stock company which resolved the problem of low mining efficiency,low security and imbalance with the below parallel thick and large ore body.Practice proved that mining steeply-inclined thin orebody with medium-deep hole high sublevel stoping method was feasibility.
