本矿为以冶炼粗铅为主,矿山生产为铺的采冶联合企业。冶炼所需铅矿石75％外购,25％的矿量本矿开采。加之本矿矿山生产缺乏采装设备,以及矿体的地形地质条件及赋存状况等诸因素,矿块之回采我们采用了工作面沿全矿房(块)推进的一步骤回采的下向梯段全面空场手工采矿法,现作一总结介绍仅供参考。 The mine is mainly smelting lead, mine production shop for the mining and metallurgical joint ventures. Smelting required 75% of the lead ore purchased, 25% of the mining capacity of the mine. Coupled with the lack of mining equipment mining equipment, as well as the ore body topography and geological conditions and occurrence conditions and other factors, the mining of mining we use the face of the whole mining house (block) to promote a step back to the ladder Paragraph comprehensive empty field manual mining method, now make a summary introduction is for reference only.
