1984年,我队在省局探矿部门的关怀指导下,引进和推广了金刚石回转冲击钻探技术。先后在6个矿区推广使用,其中有3个矿区地层比较复杂,岩心破碎易堵,回次进尺短,上班人员忙于起下钻具,劳动强度大,同时取心困难,推广回转冲击钻探技术以后,效率和质量都有大幅度的提高。截至1987年底 In 1984, our team introduced and popularized the diamond rotary impact drilling technology under the guidance of the care of the prospecting department of the provincial bureau. Successively in 6 mining areas to promote the use, of which there are three more complex ore strata, core breakage easily blocked, back into the footage is short, working staff are busy lifting the drill, labor-intensive, coring difficulties at the same time, the promotion of rotary impact drilling technology , Efficiency and quality have greatly improved. As of the end of 1987
