摘要
文中阐述了在金矿勘探中应用潜孔锤反循环连续取心(样)的优越性;介绍了自行研制的贯通式潜孔冲击器;分析了反循环连续取心(样)的机理.
Some superiorities of using down hole hammer counter circulation type continuous coring (sampling) method in gold ore exploration are expounded in this paper. A description of down hole percussion device of through type developed by ourselves is given. In addition, the mechanism of the counter circulation type continuous coring (sampling) device is analysed.
