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

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.
