随着我国金属矿采矿规模和科技水平的提高,采矿方法得到迅速发展。空场采矿法、充填采矿法、崩落采矿法等发展较快。空场法中的VCR法和阶段深孔台阶崩落采矿法首先在我国试验成功。随后这些高效率的采矿方法在国内多家大型矿山得到推广应用。充填采矿法先后采用干式、分级尾砂 With the improvement of the scale and technological level of China’s metal mines, mining methods have been rapidly developed. Open field mining method, filling mining method, mining and other development of the fast. VCR method and stage deep-hole step-down mining method in the empty-field method were successfully tested in our country. These high-efficiency mining methods were subsequently promoted and applied in several large domestic mines. Fill mining method followed by dry, graded tailings
