| 摘 要： | 针对栾川钼矿地质结构复杂、地下采空区交错纵横，采空区底板凹凸不平开孔困难，普通钻进容易造成钻孔偏斜的情况，为解决矿区面临的勘探技术难题，研究试验了以潜孔锤反循环钻探技术为核心，集成多种先进的钻探机具，采取人工造孔法、下套管导向法或实时控制参数法等钻探工艺，顺利在采空区底板打孔并钻穿多层采空区，取得了良好效果。

| Abstract: | According to the complex geological structure in molybdenum mine of Luanchuan with crisscross underground mined-out areas and uneven mining floor, experimental research was made on drilling equipment integrated various advanta-ges which took reverse circulation DTH hammer drilling technology as the core to solve the exploration difficulties in this mining area.The artificial hole-making, casing guiding, or real time parameter control methods were adopted, the con-struction was completed with good effects. |
