摘要

本文介绍了无底柱浅孔留矿法在矿山开采中的应用情况,从采场结构参数和回采工艺方面对无底柱浅孔留矿法进行了综述,取消了传统浅孔留矿法底部结构,增加出矿进路,通过电动装岩机出矿,脉外巷道运输,提高了劳动效率、矿体回采率和采矿作业安全,降低了采矿贫化率。
        This paper introduces the application of shallow hole retention method without bottom pillar in mining, summarizes the method of shallow hole retention without bottom pillar from the aspects of stope structure parameters and mining technology, and cancels the bottom structure of traditional shallow hole retention method. The mining dilution rate is reduced by increasing the ore drawing route, drawing ore by electric loader and transporting the roadway outside the vein, so as to improve the working efficiency, the recovery rate of orebody and the safety of mining operation.
