摘　　要：分析了一种类型金矿的地层复杂性和传统的金刚石回转钻进工艺存在的系列问题，通过应用实例指出贯通式气动潜孔锤反循环连续取心（样）钻进技术可以大幅度提高复杂地层金矿勘探效果。The complexity of strata of a kind of gold deposit and problems existed in conventional diamond rotary drilling technique are analyzed. A new technique called reverse circulation continuous coring (sampling) drilling by hollow - through air DTH hammer has been developed and applied in order to solve those problems. Practice has proved that this new technique can improve drilling rate and reduce cost sharply and has some other advantages.
