为了发展我国的采矿工业,研究一下凿岩的现代技术水平是很有益处的,本文拟介绍世界各国在近几年来凿岩技术的研究现状及其发展的途径。一、压气冲击凿岩的研究现状压气冲击凿岩已有数十年的历史了,二次世界大战期间应用硬质合金凿岩还只处于萌芽阶段,而在大战之后,特别是近十年来各国都普遍采用了深孔凿岩,亦是在二次大战期间及其后才兴起的一种采矿技术,然而在最近几年来各国的采矿科学工作者又在沿着各种不同的途径努力促使凿岩技术发展,其中苏联的学者们所获得的成就尤为显著。
In order to develop China’s mining industry, it is beneficial to study the modern technology of rock drilling. This paper introduces the research status and development of rock drilling technology in various countries in the world in recent years. First, the current research status of the impact of pressure rock drilling rock pressure impact has been decades of history, the application of cemented carbide drilling during the World War II is still in its infancy, but after the war, especially in the past decade countries Deep-hole drilling was commonly used and was also a mining technique that emerged during World War II and beyond, however in recent years mining scientists in various countries have been working hard in various ways to promote chiseling The development of rock technology, of which the Soviet Union scholars have made particularly remarkable achievements.
