金刚石岩心钻进法,特别是对于坑内进行钻探工作来说,是一种有效的先进的方法。过去由于我国金刚石钻探技术发展缓慢,生产矿山的探矿工作主要靠坑探,且工作量很大。有色金属和黄金矿山的年坑探工作量占掘进总量的30～40％。采用坑探方式费工、费钱、费料、费时、常造成探矿落后于采矿的被动向面,而且因需运出大量的废石,与采矿争运输,影向采矿工作的正常进行。 1969年我们开始探索用人造金刚石于钻探,1974年取得了基本或功,为我国推广应用金刚石钻探技术开造了一条新路,这也促进了坑内钻探技术的发展。特别是我们自己已研制的坑内钻机推广应用后,使坑内钻探的工作量有了较大幅度的增长,並取得了良好的经济效
Diamond core drilling method, especially for drilling in the pit, is an effective advanced method. In the past due to the slow development of diamond drilling technology in our country, the prospecting work in the production of mines was mainly based on pit exploration and the workload was very heavy. Non-ferrous metal and gold mines accounted for 30% of total excavation work. The use of pit exploration method of work, costly, costly, time-consuming, often resulting in prospecting behind the passive mining face, but also because of the need to transport a lot of waste rock, and mining dispute transport, shadow mining normal work. In 1969, we began to explore the use of synthetic diamond in drilling, made in 1974, the basic or meritorious service for our country to promote the application of diamond drilling technology to create a new road, which also contributed to the development of intra-pit drilling technology. In particular, the development and application of the in-hole drilling rig that we have already developed have greatly increased the workload of drilling in the pit and achieved good economic efficiency
