我局在部、局有关部门热情支持与协助下，金刚石钻探从1974年下半年开始试验至现在已经13年了，累计完成工作量642227m，占固体矿产钻探的53.89％，开动台数仅占固体矿产钻探的49.35％，从1982年起已基本实现固体矿产钻探金刚石小口径化，台月效率471m，较固体矿产合金、钢粒钻探（大口径，下同）317m提高48.6％，台年进尺2414m，较固体合金、钢粒钻探1683m提高43.4％。实践充分证明，由于采用金刚石钻探，则钻速提高约50％，相对缩短地质勘探周期50％左右，优质孔率提高17.9％，钻头进尺35.0m，每米节约4.46元，累计节约262.54万元（如按计划单位成本则节约更为显著）。我们及时应用金刚石钻探这一重大科技成果，为加快我省地质找矿速度，和地质工作的持续发展做出了应有的贡献，并为我局开创探矿工程新局面打下坚实基础。
With the enthusiastic support and assistance from the relevant departments of the Ministry and the relevant bureau, diamond drilling has been underway for 13 years since the second half of 1974 and the total workload has been 642227m, accounting for 53.89% of the drilling of solid minerals. The number of drilling operations only accounts for the solid mineral Drilling 49.35%, since 1982 has been basically achieved a small diameter of solid mineral drilling diamond, Taiwan efficiency of 471m, solid mineral alloy, steel drilling (large diameter, the same below) 317m increased 48.6%, Taiwan footage into 2414m, Compared with solid alloy, steel drilling 1683m increased 43.4%. Practice has proved that due to the use of diamond drilling, the drilling rate increased by about 50%, a relative shortening of the geological exploration cycle of about 50%, 17.9% increase in high-quality drilling, drilling footage 35.0m, saving 4.46 yuan per meter, saving a total of 2.6254 million yuan If the cost per unit of plan is more significant savings). We timely application of diamond drilling this major scientific and technological achievements, in order to speed up the geological prospecting speed in our province, and the continued development of geological work has made its due contribution and lay a solid foundation for our bureau to open a new prospecting project.
