派-布拉克铅锌矿难采矿体采矿方法研究

Research on Mining Method for the Difficultly-Mined Orebody in Pai-Bulake Lead-Zinc Mine

派-布拉克铅锌矿的矿体赋存形态复杂,除采用分段空场法和浅孔留矿法完成部分矿体回采工作外,其他矿体难以采用这两种采矿方法的一般性方案进行回采。根据矿体的具体赋存形态,结合现有工程布置情况,提出了各种类型难采矿体的回采方案,并且在部分采场成功的进行了试验。

The occurring shapes of the orebodies in Pai-Bulake Lead-Zinc Mine are very complex.The some of orebodies can be mined with sublevel open stoping and shallow-hole shrinkage stopping,but the other orebodies is very difficult to be mined with the general schemes of the two mining methods.According to the occurring shapes of the various difficulty-mined orebodies and the conditions of the existing projects,some stoping schemes were put forward,experiments were carried on successfully in some stopes.
