我局进行钻探勘察的地区地质,多属火成与变质岩石,硬度在5～7之间,一般使用钻粒法钻进。而使用钻粒的方法,仍沿用伪满大把灌的补给法,这样既影响钻探工程的质量与效率,又增加材料的消耗,提高了成本。在今年质量检查运动和节约运动中,钻探队同志努力钻研,将苏联式和旧日本式的钻粒使用法相给合,试制成钻粒供给器。经试验证明,基本上改变了大把灌补给法的缺点,提高了钻进效率。兹将钻粒供给器试用情况发表于下,希钻探同志进一步推广。
Bureau of drilling geological survey in the region, mostly belong to the fire and metamorphic rocks, the hardness of 5 to 7, the general use of drilling method of drilling. The use of drill method, still using the puppet Manchuria recharge method, so that not only affects the quality and efficiency of drilling projects, but also increase the consumption of materials, increased costs. In this year’s quality inspection campaign and conservation campaign, the drilling team comrades worked hard to study the Soviet-style and the old Japanese-style diamond particles to use law to try to make a diamond feeder. The test proved that basically changed the shortcomings of a large irrigation method to improve the drilling efficiency. The trial of the pellet feeder will be published here, and the next drilling by Shek Pik will be further promoted.
