银洞坡金矿区钻探施工技术及其工艺
<title>illing Technology Used in Yindongpo Gold Mine
【摘要】 介绍了银洞坡金矿区针对孔斜严重、岩心采取率低、钻孔坍漏超径等复杂难题,采用金刚石绳索取心钻进、初级定向钻进和护孔堵漏的经验和教训,并对大型固体矿产详查与勘探实施钻探工程总结出几点体会。
【Abstract】 <abstract>perience and lessons, from diamond wire line core drilling, primary directional drilling and borehole wall protection, for solving the problems of severe deviation, extremely low core recovery, borehole leakage and cave-in, were introduced. Some experiences of exploration drilling for large mine were summarized out.
