1985年我队104机在某矿区西部施工2/ZK42号钻孔,使用TK—60S绳索取心冲击回转钻具(冶金部第一冶金地质勘探公司探矿技术研究所研制),钻进厚层“打滑”地层。全孔用冲击回转钻进总进尺230米,获得较好效果,现介绍如下: 施工条件概况 1.地质情况与钻孔技术参数 2/Z K42号钻孔设计深度为350米,开孔倾角83°,方位角284°,所钻地层除开孔段和终孔段有少量硅化灰
In 1985, our team 104 drilled 2 / ZK42 in the western part of a mining area and used TK-60S rope coring impact rotary drilling tool (developed by the First Metallurgical Geological Prospecting Company Exploration Technology Institute of the Ministry of Metallurgy) to drill thick “ Slippery ”formation. Full hole impact rotary drilling total footage of 230 meters, get better results, are described below: Overview of construction conditions 1 geological conditions and drilling technical parameters 2 / Z K42 drilling depth of 350 meters, opening angle 83 °, azimuth angle of 284 °. The drilled formation has a small amount of silicified ashes except for the open section and the final section
