摘要
根据铜坑矿92#矿体的开采现状,提出了单元矿块堑沟连续推进崩落法,以缩短采准时间,减少万吨采掘比,提高回采安全性,增加矿山效益。
Based on the current state of 92# orebody extraction in Tongkeng Mine, a trench-continuously-advanced caving method for unit blocks was put into operation, thus shortening preparation time, reducing development ratio per 1000t, improving the safety of mining and increasing the mines benefits.
