摘要
针对四川会理县拉拉铜矿外围深部找矿深孔钻探,选用国产全液压钻机,并采取相对应的钻探技术措施,在复杂地层条件下成功施工孔深2067.68 m钻孔。介绍了该钻孔的钻探技术措施。
China-made fully hydraulic drilling machine was applied in the periphery of Lala copper mine for deep prospecting with relative drilling technical measures.A 2067.68 m depth borehole was successful constructed in the complex formation.The paper introduced the drilling technical measures.
