5M~3前装机于76年12月在我矿开始使用。我们主要用它进行旨在降低矿石贫化和损失的分采工作。我矿两岔岑1230米水平,矿石上面复盖有2～4米厚的风化岩层,过去采用4M~3电铲采装,贫化和损失率均高于设计指标4％,浪费了矿石资源和给选矿造成困难,现在使用前装机分采后,前装机成功地将复盖层“剃光“把矿体露出来进行分采,据测量计算,贫化和损失率降低在1％以下。前装机在5～18°坡道上作业,有时甚至
5M ~ 3 installed in December 76 in mine started to use. We mainly use it to carry out sub-division work aimed at reducing ore depletion and losses. I mine two fork Cen 1230 meters level, the ore covered with 2 to 4 meters thick weathered rock formation, the past 4M ~ 3 electric shovel mining, depletion and loss rates were higher than the design indicators of 4%, a waste of ore resources And difficult to beneficiation, now installed before the use of sub-mining, the former installed successfully cover the cover “shaved” to expose the ore body for sub-mining, according to the measurement, depletion and loss rate decreased below 1%. Before the installation of 5 ~ 18 ° ramp work, and sometimes even
