    摘要
  • 采用车载风动正循环潜孔锤+合金刮刀钻进工艺，提出了一套适用于盖层厚度小于100 m、地下水埋深大于100 m的浅覆盖区1：5万化探方法技术，方法技术包括采样粒级、采样层位、采样网度、样品收集等内容。选择玉海外围等具有找矿潜力的覆盖区开展方法技术有效性验证工作，覆盖区内圈定的异常不仅很好的反映了已知隐伏矿床，而且依据覆盖区内圈定的异常，开展异常查证工作实现玉海矿区外围覆盖区内取得找矿新突破，新圈定铜矿体5条，扩大了矿床规模。研究提出的1：5万车载浅钻化探方法技术组合在新疆东天山玉海地区以侵入岩为赋矿岩体的覆盖区内找矿是有效的。
    By adopting the drilling technology of six-wheel drive vehicle pneumatic positive circulation DTH hammer + alloy scraper, a set of 1:50,000 geochemical exploration method has been proposed for the shallow overburden area with the thickness of cap layer less than 100m and the depth of groundwater more than 100m. This method includes sampling size, horizon, grid and sample collection. In this paper, the covered area of ore-prospecting potential surrounded the Yuhai deposit has been chosen to carry out the validation work. The results show that the delineated abnormal in covered area not only well reflects the known concealed ore deposit, but also has new prospecting breakthrough in the periphery covered area of the Yuhai deposit based on the anomaly verification work, where 5 new copper ore-bodies has been delineated and the scale of the Yuhai deposit expands. Therefore, the 1:50,000 vehicle-mounted shallow drilling geochemical exploration method and technology combination proposed in this study are effective in prospecting in the overburden area with intrusive rock as host rock mass in Yuhai area, east Tianshan Mountains, Xinjiang.
