在提高岩石破碎质量的同时减少抗水炸药的用量,是最重要的课题之一。解决这个问题可以大大地改善穿爆作业的技术经济指标。降低含水岩层的穿爆作业成本的途径之一,是用廉价的不抗水炸药代替昂贵的抗水炸药。装填非抗水性炸药之前,须将炮孔内
It is one of the most important issues to improve the quality of rock crushing and reduce the amount of anti-explosives used. To solve this problem can greatly improve the techno-economic indicators of wearing explosion operations. One of the ways to reduce the operating cost of wearing strata in aquifers is to use inexpensive non-water-resistant explosives instead of expensive water-resistant explosives. Prior to filling non-water-resistant explosives, the inside of the hole shall be drilled
