我国的金刚石钻进起步较晚,但发展很快。自1963年研制成功单晶人造金刚石以来,品种不断增加,质量不断提高。后来开始研究聚晶人造金刚石,70年代初用于钻探生产。70年代开始研究复合材料,聚晶型复合片现在也已开始用于生产。在钻头制造上,60年代开始采用冷压浸渍法制造人造金刚石孕镶钻头,在此基础上研究热压浸渍法,取得较快进展。此后相继研究与使用敲击浸渍法、低温电镀法和镶片法,从而保证了钻探生产需要的各种金刚石钻头。钻探生产效率不断提高,金刚石钻探工作量逐年增大。自1966年至1984年用金刚石钻探勘探了30多个矿种,累计钻
China’s diamond drilling started later, but developed rapidly. Since the successful development of single crystal artificial diamond in 1963, the varieties have been constantly increasing and the quality has been continuously improved. Later she studied polycrystalline diamonds and used it for drilling production in the early 1970s. Commencement of composite materials research in the 1970s, polycrystalline composite films have now begun for production. In the manufacture of drill bits, artificial diamond inlaid drill bits were manufactured by cold-pressure impregnation in the 1960s. On the basis of this study, hot dip impregnation method was developed and rapid progress was made. Since then have been studied and the use of percussive dipping method, low temperature plating and veneer, thus ensuring the production of diamond drilling a variety of needs. Drilling production efficiency continues to increase, diamond drilling workload increased year by year. Over 30 mines have been drilled with diamond from 1966 to 1984, with a total of drilling
