地下深孔崩矿,是高生产率采矿方法的基础,是苏联在坑内作业技术革新上最杰出的成绩之一。近几年来,由于苏联成功地创造了各种新式的钻眼设备与爆破器材,深孔崩矿不仅显著地提高了劳动生产力,而且节约了材料,不断的降低了采矿成本和改善了安全技术与采矿强度。例如工人不进入采场内作业,只在采准坑道内钻眼,即避免了工作时冒顶的威协。我 Underground deep-hole collapses are the basis of high-productivity mining methods and one of the most outstanding achievements of the Soviet Union in pit technical innovation. In recent years, as the Soviet Union has successfully created various new types of drilling equipment and blasting equipment, deep-hole collapse not only significantly increases labor productivity but also saves materials, continuously reduces mining costs and improves safety technology and Mining intensity. For example, workers do not enter the stope and only drill holes in the excavation tunnel, which avoids the threat of caving at work. I
