在“打破洋框框,走自己工业发展道路”方针的指引下,我队组成了以工人为主体、有领导干部和技术人员参加的三结合小组,对原为班加钻的辅助工具-“筒锹”进行了技术改造.经过长期实践,于1972年发展成手摇钢丝绳冲击钻.用这种钻机先后完成了两个花岗岩风化壳稀土矿床的普查、勘探工作,面积达40平方公里,打了五千多个钻孔,总进尺四万多米,成为该类型矿床的主要勘探手段,为国家寻找稀土矿产资源作出了贡献.
Guided by the guideline of “Breaking the Western Frames and Taking the Path of Industrial Development”, our team has formed a three-in-a-small group with workers as the main body, leading cadres and technical personnel, After long-term practice, it developed into a hand-cranked wire rope impact drill in 1972. With this kind of drilling rig, two surveys of granite weathered crust rare earth deposits have been completed successively, with an area of 40 square feet Km, hit more than 5,000 drill holes, a total footage of more than 40,000 meters, becoming the main exploration means of this type of deposit, for the country to find the contribution of rare earth mineral resources.
