为了加快有色矿山地质与生产探矿速度,中国有色金属工业总公司决定在全国有色矿山大力推广使用小口径人造金刚石钻探新技术。前冶金部有色司在1975年先后投资兴建了赤峰有色矿山钻机修造厂和北京怀柔有色矿金刚石钻头、钻具厂,分别生产配套的钻机和钻头、钻具,供矿山探矿使用。随着产品的陆续投产,已在矿山生产中日益发挥出重要的作用。怀柔有色矿钻头钻具厂,设备齐全,技术先进。于1979年首次成批生产出合格人造金刚石钻头,继而品种、规格不断增加。1980年又开始生产φ36和φ45成套钻具。几年来由于信守合同,服务周到,产品质美价廉,以及矿山用户大力支持,因而销路不断扩大,赢得了信誉,在全国有色、黑色、黄金、化工等部门的矿山,已有24个省市的近100个单位大量使用,受到了用户欢迎。
In order to speed up the geology and production prospecting of colored mines, China Nonferrous Metals Industry Corporation decided to vigorously promote the use of small-caliber synthetic diamond drilling technology in non-ferrous mines throughout the country. In 1975, the former Ministry of Metallurgical Affairs of the Ministry of Metallurgy invested and built the Chifeng Nonferrous Mine Rig Repair Factory and the Beijing Huairou Nonferrous Metal Diamond Bit and Drilling Tool Factory, respectively producing matching drilling rigs and drill bits and drilling tools for mine prospecting. With the continuous operation of the products, they have been playing an increasingly important role in the production of mines. Huairou non-ferrous mine drill bit, fully equipped, advanced technology. In 1979 for the first time in batches to produce qualified synthetic diamond bits, followed by varieties, specifications continue to increase. In 1980, it started to manufacture φ36 and φ45 complete sets of drilling tools. Over the past few years due to abide by the contract, courteous service, product quality and cheap, and strong support of mine users, which continue to expand sales and won the reputation in the non-ferrous metals, black, gold, chemical and other sectors of the mines, 24 provinces Nearly 100 units of large-scale use, has been welcomed by users.
