近20年内,苏联采矿工业的主要发展方向是广泛采用露天采矿法开采坚硬岩矿。露天开采的重要生产环节是穿孔。为了确定穿孔技术的发展途径,作者对黑色、有色、化工、煤炭和建材部门共164个露天矿近20年内的穿孔技术经济指标进行了研究。1982年,这些露天矿共穿孔约3100万米,其中,用直径215.9毫米、244.5～269.9毫米和320毫米的牙轮钻头钻进的分别为1120、1250和60万米;螺旋钻进的为670万米。
In the recent 20 years, the main development direction of the mining industry in the Soviet Union is the widespread use of the open pit mining method to hard rock. The important part of open pit mining is perforating. In order to determine the development of perforation technology, the authors studied perforation technical and economic indicators of 164 open pit mines in the black, non-ferrous, chemical, coal and building materials sectors in the recent 20 years. In 1982, a total of about 31 million holes were drilled in these open pit mines, with 1120, 12500 and 600000 meters respectively drilled with roller cone bits of 215.9 mm, 244.5-269.9 mm and 320 mm diameters; screw holes of 670 Million meters.
