Abstract
During the reinforced concrete headframe construction in alpine areas in Northwest China, by the research and application of rapid thawing technology in pile foundation range and rapid headframe construction technology in winter, the project quality can be ensured; the construction speed of headframe pile foundation and headframe body in winter was accelerated; the time of headframe construction was shortened and the bottleneck problems of coal mine construction in alpine areas were solved.
