我队勘探的白云铁矿，伴生有稀土金属，需要综合利用，因而对钻孔质量要求高，除覆盖层外，全孔均按矿层采取率要求，为此必须把质量列为优先，应有一套完善的适合地质钻探特点的科学的质量管理办法。基于我们的经验教训并汲取国内外质量管理经验，概括起来，提出如下质量管理方法——“四个坚持，二个抓紧”：（一）坚持一切为地质满意 地质设计是钻孔质量的前提，要牢记钻探下一道工序是使用钻孔资料，要站在地质立场上去开展钻探工作。（二）坚持一切以预防为主、防治结合 优质钻
The exploration of the team of Baiyun iron mine, associated with rare earth metals, the need for comprehensive utilization, which requires high quality drilling, in addition to the cover, the whole hole by the mining rate requirements, for which quality must be given priority, there should be a Set of perfect geological drilling characteristics of scientific quality management approach. Based on our experience and lessons and drawing on the experience of quality management both at home and abroad, we put forward the following quality management methods: - “Four Adherences, Two Grasps”: (1) Insisting on Geological Satisfaction for All Geological Design is the Prerequisite for Drilling Quality, It is important to bear in mind that the next step in drilling is the use of borehole data, and that it is necessary to carry out drilling work from the geological standpoint. (B) adhere to all the main prevention, prevention and control combined with high-quality drilling
