一、概况哈密黄山地区的普查找矿工作,始于八二年。开始以汽车钻做了些地表浅部的探索。同年十月前后共开动七台钻机,均为大口径钢粒合金钻。完成十二个孔,进尺2471米。八三年开动五台钻机,其中两台小口径钻机进行试验性钻进,完成三个孔,进尺1636米,平均台月效率227米,小时效率1.29米,纯钻率24％。通过年终总结,认为小口径钻进只要技术管理、材料供应能跟上,提高效率的潜力是很大的。八四年开动三台小口径钻机,共完成20个孔,
I. Overview The general search for mines in the Huangshan area of Hami began in 1982. Began to do some exploration of surface shallows with car drilling. In the same year in October of the same year, a total of seven drilling rigs were started, all of which are large-diameter steel alloy drills. Twelve holes were completed and the footage was 2471 meters. In 1983, five drill rigs were started, two of them were used for experimental drilling, three holes were completed, and the footage was 1,636 meters. The average monthly efficiency was 227 meters, the hourly efficiency was 1.29 meters, and the pure drilling rate was 24%. Through the year-end summary, it is believed that as long as technology management and material supply can keep pace with small-diameter drilling, the potential for improving efficiency is great. In 1984, three small-diameter rigs were started and 20 holes were completed.
