中文摘要: 近水平极薄矿体由于矿体薄、倾角几乎水平,爆破的矿石难以自溜,导致生产效率低、贫化损失大。为提高矿山生产效率,结合南温河钨矿极薄矿脉开采现状,提出了双侧侧向抛掷爆破采矿法,利用抛掷爆破技术将矿石直接抛入受矿槽内,从而很大程度上提高了生产效率。经现场试验采场开采与之前才用的采矿方法对比发现,生产效率有着明显的提高,贫化损失率都可控制在10%以内,极大的提高矿山的经济效益。
中文关键词: 近水平极薄矿体  采矿工艺  抛掷爆破  
Abstract:The near horizontal extra-thin orebody has low productivity, low loss of depletion due to the thin ore body, the dip is almost horizontal, and the blasted ore is difficult to slip. In order to improve the mine production efficiency, combined with the current situation of the mining of the extra-thin orebody of the Nanwenhe tungsten mine, a double-sided lateral throwing blasting mining method was proposed, which used the throwing blasting technology to throw the ore directly into the receiving tank, thereby greatly improving the production. effectiveness. Compared with the previously used mining methods, the field production has a significant improvement in production efficiency, and the rate of depletion loss can be controlled within 10%, greatly improving the economic benefits of the mine.
