摘要
针对缓倾斜薄矿脉采用传统削壁充填法开采时存在的薄弱环节,采用抛掷爆破接顶充填技术,取代了80％以上的人工充填量,并有效地控制了采矿贫化损失,改善了劳动条件,从而大幅度地提高了采场劳动生产率,取得了显著的经济效益与社会效益。
Some problems still exist when mining flat-dip thin vein with resuing-and-filling method. However, when the technology of tightened filling with oriented pin-point blasting is adopted, over 80% of manual filling work is saved, the dilution and loss of ores effectively controlled and working conditions improved, resulting in a big increase in stope productivity and yielding remarkable economic effect and social benefits.
