硬岩爆破破碎是最重要的工艺过程,无论掘进、回采和矿物原料加工的各个后继工艺过程,还是整个企业的技术经济指标,以及劳动安全条件都取决于完成这一过程的质量。苏联国家矿山技术监督局在分析各类采矿活动中发生不幸事故的原因和次数后表明,爆破作业的不幸事故次数占总次数的6～8％。近 Hard rock blasting and crushing are the most important processes, regardless of the successor processes of heading, mining and mineral processing, or the technical and economic indicators of the entire enterprise, as well as the conditions of work safety, all depend on the quality of the completion of the process. After analyzing the causes and the number of unfortunate accidents in various mining activities, the State Bureau of Minerals and Technology Supervision of the Soviet Union showed that the number of unfortunate accidents in blasting operations accounted for 6 to 8% of the total number. near
