一、“中国岩金勘查第一深钻”顺利终孔,终孔孔深4006.17 m,创多项全国钻探新纪录“中国岩金勘查第一深钻”——山东莱州三山岛西岭金矿区ZK96-5孔终孔,终孔深度4006.17 m,终孔口径75 mm。该孔由山东黄金集团地勘公司设计,山东省地矿局第三地质矿产勘查院负责施工,设计孔深4000 m,于2010年9月18日开钻,2013年5月29日终止钻进,历时985天。如此超深孔小口径地质岩心钻探,在我国钻探史上尚属首次,对钻探设备、机具、工艺以及
First, the “China’s deep exploration of gold and gold rock drill,” the smooth final hole, the final hole depth of 4006.17 m, creating a number of new national record of drilling, “China’s first exploration of deep gold rock exploration” - Shandong Laizhou Sanshandao Xiling gold ZK96-5 hole end hole, the final hole depth 4006.17 m, the final hole diameter 75 mm. The hole was designed by the Geological Exploration Company of Shandong Gold Group and the Third Geological and Mineral Exploration Institute of Shandong Provincial Bureau of Geology and Mineral Resources. The hole was designed to be 4000 m deep and drilled on September 18, 2010 and terminated on May 29, 2013 , Which lasted 985 days. This ultra-deep hole small diameter geological core drilling is the first time in China’s drilling history, drilling equipment, machinery, technology and
