1958年，地质部在探矿工程科研工作方面依据第二个五年计划期间探矿技术的发展方向和科研远景规划以及当前生产对科研工作的迫切要求与可能，初步拟定了二十个研究题目（也有与有关部门协作的项目），其内容大致如下：1．在各种岩石中岩心钻进技术的改进与研究着重在：各种地质条件下硬质合金钻头合理结构的研究与改进、钻头本体规格的合理选择、硬合金成分几何形状对效率的影响以及金刚石钻头铸镶工艺过程的研究等。
In 1958, the Ministry of Geology preliminarily formulated 20 research topics (also related to prospecting engineering research work) based on the direction of development of prospecting technology and the prospect of scientific research during the second five-year plan and the urgent requirements and possibilities of current production for scientific research Collaboration with relevant departments of the project), its contents are as follows: 1. In a variety of rock core drilling technology improvements and research focused on: a variety of geological conditions of carbide research and improvement of the reasonable structure, a reasonable choice of bit body size, hard alloy geometry and the impact of the efficiency of diamond Drill casting inlay process of research.
