| Abstract: | This paper describes the application of SYZX75 wire-line coring hydro-hammer in hard and broken formation of Delenuoer iron deposit in Subei County of Gansu Province and summarizes the experience of inclined hole drilling construction with the drill. The practice showed that by using SYZX75 wire-line coring hydro-hammer, the round trip meterage and drilling efficiency were greatly enhanced, core blockage in broken formation was effectively overcame and core recovery was improved in broken formation; all these contributed to control the inclination in inclined hole drilling construction. |
