Drilling Construction Technology of Uranium Ore Exploration in Deep Shazijiang Deposit and Its Peripheral Ones

摘要:

总结了广西资源县沙子江矿床深部及外围铀矿普查钻探施工技术。在花岗岩地层钻进中，解决了孔内漏水、掉块、垮孔及金刚石钻头寿命短、钻杆和钻杆接头磨损、钻孔弯曲等一系列问题。为在花岗岩地层钻进中积累了宝贵的钻探施工经验。

Abstract:

The paper summarized the construction technology of uranium ore exploration in deep Shazijiang deposit and its peripheral ones in Guangxi. Difficulties of block-falling, borehole collapsing, short service life of diamond bit, wearing of drilling pipe & the joint and the borehole bending were solved in granite stratum drilling. The valuable experience was accumulated for granite stratum drilling.
