为了保证满足国民经济建设对地下资源日益增长的需要，保证在第二个五年计划期内，矿产储量任务的超额完成，摆在我们地质工作者面前的任务是：鼓足革命干劲，想尽一切办法，从各个方面来加快矿产勘探速度，降低勘探工程的成本。共中具体对钻探工作者的要求是：在保证质量和保证安全的基础上，尽快的提高钻进效率。按照岩石的可钻性，在七级以上坚硬岩石中应采用钻粒钻进的方法。钻粒钻进，在勘探国家急需的有色金属、稀有金属的矿产上，意义更加重要，因为这些矿产多半埋藏在坚硬的岩层中。同时从地质部几年的生产情况来看，钻进七级以上坚硬岩石的实物工作量，一般占总工作量40％左右。因此在现有条件下，如何进一步提高钻粒钻进速度的问题，是迫待大家深入研究解决的问题。
In order to ensure that we meet the growing needs of the underground economy for the construction of the national economy and that over-fulfilling the tasks of mineral reserves within the second five-year plan period, the task before our geological workers is to: Suffer the revolutionary drive and try our best We will speed up mineral exploration in all aspects and reduce the cost of exploration projects. The specific requirements of the drillers in common are: to improve the drilling efficiency as soon as possible on the basis of ensuring the quality and ensuring the safety. According to the drillability of rock, drilling method should be adopted in hard rock above Grade 7. Drilling into diamonds is even more important in exploring nonferrous metals and rare metals that are urgently needed in the country because these minerals are mostly buried in hard formations. At the same time, from the production situation of the Ministry of Geology for several years, the physical workload of drilling hard rock above Grade 7 generally accounts for about 40% of the total workload. Therefore, under the existing conditions, how to further improve the drilling speed of diamond drilling is an issue that we urge everyone to study in depth.
