| Abstract: | With the increase in mining depth and development of drilling technology, supplementary exploration borehole work becomes frequent in underground coalmines. Taking underground supplementary hydrogeological exploration boreholes in mining zone 230, Getting coalmine, Jibei coalfield as example, this paper introduced the working technology and method for underground ultra-deep boreholes, summarized underground construction experiences in deep vertical drilling and provided a reference for the same kind of work in the future. |
