Application of Air Reverse Circulation Continuous Sampling Drilling Technology in a Mine Xinjiang

摘要:

通过选取合适的钻探设备和合理的钻进参数，空气反循环连续取样工艺在新疆乌什磷钒矿区取得了良好的应用效果。该工程实践表明，在缺水地区及岩矿样难采取的地层，空气反循环连续取样钻探技术取样率可达到100%，施工成本低，经济效益显著。介绍了施工设备、管材的配置及钻探施工工艺。

Abstract:

By selecting the suitable equipments and reasonable drilling parameters, good application effects were obtained by air reverse circulation continuous sampling drilling process in Wushi phosphorus vanadium mine of Xinjiang. The practice shows that this technology can get 100% sample recovery even in arid area and difficult sample recovery formation with low construction cost and effective economic benefits. The paper introduces the construction equipments, pipe configuration and drilling technology.
