露天钻孔作业不仅是矿山生产的第一道工序,同时也是关键工序。钻孔质量的好坏及效率的高低,直接影响着爆破、铲装、运输等工作,对整个矿山的生产和经济效益起着举足轻重的影响。然而,自40年代联邦德国Salzgitter公司研制第一台有效的切削回转钻机及50年代初比利时的Stenuick公司研制第一台有效的潜孔钻机先后问世以来,均主要应用于露天矿山。此后,世界各国对露天钻机进行了大量的研究和改进工作,并研制出多种类型和规格的露天钻机,对提高
Open-hole drilling operations are not only the first process of mine production, but also the key process. The quality of drilling and the level of efficiency directly affect the blasting, shoveling, transportation and other work, the production and economic benefits of the entire mine plays a decisive influence. However, since the first effective rotary drilling rig developed by Salzgitter AG of the Federal Republic of Germany in the 1940s and the first effective downhole drilling rig developed by Stenuick Company of Belgium in the early 1950s, it has been mainly used in open pit mines. Since then, various countries in the world have conducted extensive research and improvement work on open-air drilling rigs and have developed various types and specifications of open-air drilling rigs,
