摘要
针对冬瓜山铜矿大团山矿体23#矿柱开采工程背景,进行了23#矿柱安全高效回采技术可行性论证,详细介绍了矿柱回采顺序及中深孔分段空场采矿法回采工艺,可为矿山今后残矿回采提供借鉴。
Aiming at the stoping engineering background of No.23 ore pillar in Datuanshan orebody of Dongguashan copper mine,feasible evaluation on the safety and high-efficiency stoping technology is carried out.The stoping sequence and medium-deep hole subsection open stope mining method is introduced in detail,which may provide refferrences for the recovery of remnant ore in future.
