Abstract
This paper analyses drilling freezing hole vertical airshaft in HuiChun mine.With the actual conditions and technical requirements taken into account,the relevant construction technologies are given.And it is pointed out different drilling coefficient and drilling tools should be applied to different rock layer,and the cement slurry be mixed accordingly.The technique is capable of ensuring the quality of hole,shortening freezing time and total period of construction.关键词
