为了提高岩芯钻探技术水平、多打钻、快找矿,为加速我国四化建设多做贡献,我公司在冶金部地质局的关怀和冶金部地质研究所的大力协助下,从1974年起,试验、推广了人造金刚石钻进技术,取得了较好的技术经济效果.下面谈谈我们的体会和今后的设想. 基本情况我公司人造金刚石钻进技术试验是1974～1975年首先在215队大厂矿区三台钻机全面展开的,1976年,在认真总结经验的基础上,又先后在271队、273队、204队、270队和215队的新矿区扩大试验并推广使用.截至去年6月,公司在八个矿区的砾岩、灰岩、片岩、页岩、砂岩、花岗岩等四至九级岩层中共竣工282个钻孔,平均孔深538米,最深922米;总进尺151714米,平均台月效率352.4米,平均小时效率1.36米,平
In order to improve the level of core drilling technology, drilling more and finding ore faster and making more contributions to speeding up the construction of the four modernizations in our country, our company, with the great assistance of the Ministry of Metallurgy and Geology Bureau of Geology and the Geological Institute of the Ministry of Metallurgy, started from 1974 , Testing, promotion of synthetic diamond drilling technology, and achieved good technical and economic results. Let’s talk about our experience and future ideas. Basic situation My company artificial diamond drilling technology test 1974-1975 first in the 215 team Dachang mining area in full swing three rigs, in 1976, on the basis of serious sum up experience, and has 271 team, 273 team, 204 team, 270 team and 215 team of new mining area to expand the test and promote the use of as of last year 6 In August, the company completed a total of 282 boreholes in four or nine rock formations including conglomerate, limestone, schist, shale, sandstone and granite in the eight mining areas with an average hole depth of 538 meters and a maximum depth of 922 meters. The total footage was 151,714 meters, with an average of Taiwan and Taiwan efficiency of 352.4 meters, the average hourly efficiency of 1.36 meters, flat
