连续采矿-顶板诱导崩落综合技术在大厂铜坑矿的研究与应用

Research and Application of Integral Technology of Continuous Mining-Induced Roof Caving

对大型贫矿体的开采,用充填的采矿方法经济上不可行,用传统的空场法或崩落法存在资源整体回收率低、后期地压难控制等问题。对此采用古德生教授提出的"以矿段为回采单元、矿段间不留矿柱"的连续开采方式,并相应地用一定的诱导工程崩落处理顶板以释放地压,在广西大厂铜坑矿92号矿体的工业试验有效地提高了资源的回收率,并用经济安全的工程手段成功控制了大的地压灾害的发生。

For large lean ore deposits,it is economically unfeasible to use the filling method and there are problems of low integral resource recovery and difficult control of ground pressure in later period if conventional open-stope or caving method is used.As a solution,Professor Gu Desheng has proposed a continuous mining method,where the ore block is taken as a stoping unit,there are no intermediate pillars between the ore blocks and induced roof caving is used to release the ground pressure.The industrial test ...
