我处自58年四季度以来,为了迅速开展新区地質勘探工作,貫彻土洋並举的方針,組織了手掘上馬,大放高产卫星,在手凹坑探大跃进的群众运动中,原来所使用的一字形碳素鋼钎头远远不能适应生产需要,为了迅速提高鑿岩穿孔速度,以提高效率完成和超額完成国家計划,如何改进钎头和提高钎头質量,就成 Since the fourth quarter of 58 years ago, in order to rapidly carry out geological exploration work in the new area and implement the principle of combining localities with foreign countries, I have organized hand-plowing and high-yielding satellites, and in the mass movement of the hand-to-toe leap forward, The original carbon-steel brazed bits are far from being able to meet production needs. In order to rapidly improve drilling perforation speed, to improve efficiency and to complete national plans, how to improve the brazing head and improve the quality of the brazing bit,
