浙江诸暨金矿属于松软急倾斜薄至中厚矿体。建矿初期,该矿采用留矿法开采,贫化、损失率很高。现改用下向分层胶结充填法进行开采。实践表明该法降低了贫化、损失率并提高了安全性,但生产能力低、劳动强度大及支护材料消耗量大。由此,作者提出并论述了垂直分条胶结充填法,可获得较好的综合经济效益并有较强的适应性。
Zhejiang Zhuji gold mine is soft and steep inclined thin to medium-sized ore body. In the early stage of construction, the ore was mined by mining method, depleted and the loss rate was high. Now switch to the next layer of cemented filling method for mining. Practice shows that this method reduces the rate of depletion and loss and enhances safety, but with low productivity, labor intensity and high consumption of supporting materials. Therefore, the author put forward and discussed the vertical strip cementing method, which can obtain good comprehensive economic benefits and strong adaptability.
