摘要
With the construction case of a bedrock well in an iron ore mine of Gansun, which was 310 mm in diameter and constructed by foam DTH hammer, the paper summed up and verified the application of foam DTH hammer technology in large diameter bedrock well construction and presents drilling technologies in different borehole sections.
