大量落矿采矿法从小直径深孔向大直径深孔的过渡是近20年来国标采矿界所探讨的问题之一,本文通过分析对比指出采用牙轮深孔采矿是可行的,并介绍了目前所用的采矿方案、钻孔机具和爆破技术,最后,指出了我国矿山采用这种方法所应解决的几个问题。
The transition from small-diameter deep hole to large-diameter deep hole in a large number of ore-dropping mining methods is one of the problems discussed by the national standard mining community in recent 20 years. This paper analyzes and contrasts that it is feasible to adopt deep- Mining program, drilling equipment and blasting technology. Finally, it points out several problems to be solved by this method in mine in our country.
