脉内斜坡道在极薄矿脉开采中的应用

随着微型无轨化设备的应用，极薄矿脉的开采有了新的突破，即：脉内斜坡道机械化开采。金厂沟梁金矿学习国外经验，结合矿体赋存条件，以布置脉内斜坡道的机械化削壁充填法进行开采试验取得了成功，在国内同类矿山的开采中具有推广意义。

THE APPLICATION OF SUBENTRYRAMP IN MINING OFEXTREME THIN LODE

With the application of miniature trackles- sized equipment , the mining of extreme thin lode has made new break through , i. e. mechanized mining within subentry ramp. Ginchanggouliang Gold Mine learned from foreign experience and combined with natural conditions of orebody , making suc- cess with carryin out mining experiment of mechanized cut wall fill method arranging in subentry ramp , having extended signifi- cance for mining in domestic mines.
