提高坑道掘進效率,首要的是使鑽眼爆破技術工作合理化,這項工作是加速有益鑛物鑛床的勘探和降低成本的重要課題之一。岩石的可鑽性和爆破性的問題,儘管是已經引起很多學者和實際工作者的注意,但到目前為止,在這些過程中的管理方面還有很多主要部份不够明確。因此,往往使電能、氣動能、爆破材料和其他材料消耗過大,特別是在勘探坑道掘進的條件下,更容易感到這一點。莫斯科地質勘探學院山地工程教研室,在蘇聯地質保鑛部所屬的不同探鑛工程項目中,對岩石的可鑽性和爆破性方面作了若干研究工作。研究結果曾推薦 One of the most important tasks for improving tunneling efficiency is to rationalize the drilling and blasting technology. This work is one of the important topics for accelerating the exploration and cost reduction of beneficial mineral deposits. Although the problem of rock drillability and explosiveness has attracted the attention of many scholars and practitioners, so far, many major parts of the management of these processes are still not clear enough. As a result, energy, aerodynamic energy, explosives and other materials are often over-consumed, especially under the conditions of exploration tunnels. The Department of Mountain Engineering, Moscow Institute of Geological Prospecting, made a number of researches on the drillability and blastability of rock in different prospecting projects under the Department of Geology and Mineral Resources of the Soviet Union. The results have been recommended
