| Abstract:With the engineering practice of the large diameter ice transmission well of a coalmine, the construction technologies of large diameter ice transmission well were summed up. The relative technologies in the drilling construction were discussed about the equipment selection, bottom hole assembly for pilot hole & reaming, the pilot hole, step reaming and well cementing; and the newly developed insulating case and casing method by lifting bar in cutting-holes and floating plug were also presented. |
