苏联矿山坑内技术作业改进上,最傑出的成就之一,即是在坑内采用深孔鑿岩爆破法。这种方法能適用于多种的采矿法,它的优点不仅在于能提高采矿采掘强度与劳动生产数率,而且也是节省材料、降低成本和改进技术安全与劳动强度的重要方法。例如工人不进入采矿场内作业,只在采準坑道内鑿眼,即避免了工作时冒顶的威胁。目前这种深孔鑿岩爆破法,不仅普遍于苏联黑色金属,而且也采用于有色金属矿山。在我国,由于硬质合金还没有普遍实行,制造深孔鑿岩的工具还没有在质量上和数量上供应大量采矿之需要,因此,还缺乏普遍推广的条件。但是在个别矿山某些采矿场的试点工作是应该而且是有条件进行 One of the most outstanding achievements in improving technical operations in the mines of the Soviet Union is the use of deep-hole rock blasting in the pit. This method can be applied to a variety of mining methods. Its advantages lie not only in improving the mining intensity and labor productivity, but also as an important method for saving materials, reducing costs and improving technical safety and labor intensity. For example, workers who do not enter the mining site work only by digging holes in the excavation tunnels, thus avoiding the risk of falling overhead at work. At present, this deep-hole drilling blasting method is not only common in the black metal in the Soviet Union, but also in non-ferrous metal mines. In our country, since the cemented carbide is not yet widely practiced, the tools for manufacturing deep-hole rock drilling have not yet met the need to supply large quantities of gold both qualitatively and quantitatively. Therefore, there is a lack of universal promotion conditions. However, the pilot work in some mining mines in individual mines should be conducted on a conditional basis
