我国金属矿山使用的钻具,包括牙轮钻头、潜孔钻头、潜孔冲击器、中小钎头,都是一种消耗性的生产工具,它们的质量好坏和寿命长短直接影响钻机的效率和穿孔成本。因此,提高钻具使用寿命的研究和加强钻具的使用管理,是一件具有重要经济意义的任务。一、基本情况金属露天矿山的钻具,在六十年代,主要应用钢丝绳冲击钻(1、202),穿孔技术长期处于落后状态,影响了矿山的生产和建设速
Drilling tools used by metal mines in our country, such as roller cone bits, down-the-hole drills, down-hole impactor and small and medium-sized drill heads, are all expendable tools for production. Their quality and life span directly affect the efficiency of drilling rigs. Perforation costs. Therefore, improving the service life of drilling tools and strengthening the management of the use of drilling tools is a task of great economic significance. First, the basic situation Metal open-pit mining tools, in the sixties, the main application of wire rope impact drill (1,202), perforation technology has long been in a backward state, affecting the production and construction speed of the mine
