当前,在矿山开发、隧硐开挖、水工建设和国防施工中,凿岩爆破作业仍是一个不可缺少的手段。因此,不断提高凿岩爆破技术水平,推广应用新型设备和工具,就成为一项十分重要的工作。增加凿岩钎头产量、提高钎头质量的问题,就是其中的一个重要内容。这方面的工作历来都受到有关领导部门、科研单位和广大矿山工作者的重视。近年来,特别是粉碎“四人帮”以来,我国凿岩工具科研成果不断涌现:中南矿冶 At present, in mine development, tunnel excavation, hydraulic construction and national defense construction, drilling blasting operations are still an indispensable means. Therefore, it is a very important task to constantly improve the technical level of rock drilling and popularization and application of new equipment and tools. One of the important issues is to increase the output of rock drill heads and improve the quality of drill heads. The work in this area has always been valued by the relevant leading departments, research institutes and mine workers. In recent years, especially since the smashing of the “Gang of Four,” the achievements in scientific research in China’s rock drilling tools have been constantly emerging:
