中文摘要:广东大宝山钼矿区地层复杂，钻孔施工中常发生漏失、掉块、坍塌垮孔、缩径等情况，易造成钻具折断，卡钻、烧钻、埋钻等事故，且取心困难。通过选择合理的钻探工艺方法、护壁堵漏措施和钻探取心技术措施，使大宝山钼矿床和北面山多金属区详查找矿钻探工作顺利完成。详细介绍了大宝山钼矿复杂地层钻探技术。

Drilling Technology in Complex Stratum of Dabaoshan Molybdenum Mine
Abstract:The stratum is complicated in Dabaoshan molybdenum mine. Leakage， block falling， borehole collapsing and diameter shrinkage often occurred and coring was difficult for drilling tool breaking， sticking， bit burning and burying. By selection of rational drilling technologies， wall protection and leakage control methods and drilling coring methods， the detailed survey and prospecting drilling were smoothly completed. The paper introduced the drilling technology in the complex formation of Dabaoshan molybdenum mine.
