以钻探代替坑探是当代矿山探矿的发展趋势.一些发达国家和地区更是如此.如美国、加拿大、澳大利亚等国的矿山都使用钻探.我国在20世纪50～60年代、矿山全部用坑探;到20世纪70～80年代,一些大型矿山采用了坑、钻联合探矿方法,不仅提高了探矿速度,同时取得了明显的经济效益;20世纪80年代以来,特别是近几年,大中型矿山采用了金刚石钻机,以钻探代替了坑探,取得了显著的经济效益.如三山岛金矿应用了泰美克251型金刚石钻机,既满足了大规模探矿的要求,又降低了探矿成本,为进口钻机更好的为矿山服务提供了借鉴.
Drilling instead of pit exploration is the trend of the development of contemporary mines, especially in some developed countries and regions such as the United States, Canada, Australia and other countries have used mines.My country in the 20th century, 50 to 60 years, all mined with pits By the 1970s and 1980s, some large-scale mines used pit and drill methods in combination with prospecting, which not only increased the prospecting speed but also obtained obvious economic benefits. Since the 1980s, especially in recent years, large and medium-sized mines Using a diamond drilling rig to drilling instead of pit exploration, and achieved significant economic benefits, such as the application of the Thai Sanyingdao 251 gold diamond drilling rig, not only to meet the requirements of large-scale prospecting, but also reduce the prospecting costs for the import Rig better provided a reference for mine service.
