武钢矿山系统的探矿工作,70年代一直使用合金和钢粒钻进及其配套装备,技术落后,影响了矿山地质工作的进展.后来,根据冶金地质系统推广地表金刚石钻探技术的经验,武钢矿山系统开始对旧钻探装备进行改造,大力推行矿山金刚石钻探新技术. 1978年,冶金部矿山司下达“钻石-300型全液压坑内岩心钻机”的研究任务(由原桂林冶金地质研究所、武钢矿山部和武钢大冶铁矿共同承担),前后经过两轮试制和试验,共施工13个钻孔,总进
Later, according to the experience of the promotion of surface diamond drilling technology in the metallurgical and geological system, the Wugang Mining System (Wugang Mining System) Began to reform the old drilling equipment, and vigorously promote the new technology of diamond mining in the mines. In 1978, the Ministry of Metallurgical Mining Division issued a “Diamond -300 full hydraulic pit core drilling rig” research mission (formerly Guilin Metallurgical Institute of Geology, Wuhan Iron and Steel Mines And Wugang Daye iron ore shared), before and after after two rounds of trial and test, a total of 13 drilling construction, the total
