摘要
随着西部大开发及国家三五八工程的开展,新疆昆仑山脉高海拔无人区成为地质找矿的重点,如何提高昆仑山脉钻孔钻探施工的效率,是当前岩心钻探施工的重点。通过白干湖钨锡矿岩心钻探的施工情况论述了该工程的施工经验和方法。
With the western China economic development and national 358 engineering development,high altitude Kunlun Mountains in Xinjiang become the focus for prospecting mineral resources.How to improve drilling efficiency in this area is an important business.Through the practice of core drilling of Baiganhu W-Sn mining area,Xinjiang,the paper discussed the construction experience and methods.
