| 摘 要： | 按常规,岩心钻探施工一般多采用金刚石绳索取心回转钻进工艺,然而在独山县半坡锑矿坚硬岩石中,回转钻进却不凑效,笔者通过采用液动冲击回转钻进工艺后,改变了钻头刻取岩石的破碎机理,克服了单一回转的＂打滑＂现象,获得理想的效果。

| Abstract: | Core drilling usually uses large diameter diamond wire-line coring rotary drilling technology,but the rotary drilling is not effective in the hard rocks in Banpo antimony deposit of Dushan.By use hydraulic impact rotary drilling technology,the fracture mechanism,surmounts the phenomena of rotary slip and gets good efficiency. |
