针对山东某金矿-130m水平以下矿体赋存条件改变,经过试验研究用机械化上向水平分层充填连续采矿法取代分段空场嗣后充填法,并针对存在问题在细节上提出了改进方案。生产实践表明,该方法安全、高效、低贫损、低成本,采矿损失、贫化率分别降低了3.7,2.6个百分点,矿山生产规模提高1倍以上,取得了充分利用资源、保护环境和提高矿山经济效益的良好效果。
Aiming at the alteration of the orebodies in a gold mine below -130m in Shandong Province, the subsequent filling method was replaced by mechanized vertical horizontal stratified filling and continuous mining instead of sub-level empty field, and the improvement scheme was put forward in view of the existing problems . The production practice shows that the method is safe, efficient, low-loss, low-cost, mining loss and depletion rate decreased by 3.7 and 2.6 percentage points respectively and the scale of production of mines increased by more than one time. It has made full use of resources, environmental protection and improvement Mine economic benefits of the good results.
