摘要
介绍了塔什店风井冻结施工主要的冻结参数,论述了风井温控系统的设计方法,并从大圈径布置冻结孔、异径冻结、温控孔保障等方面,提出了已成型井壁的保护措施,达到了冻结法施工中已成井壁完好无损的效果。
This paper introduced the main freezing parameters of Tashidian coal mine shaft freezing construction,discussed the design method of wind shaft temperature control system,and from the big circle diameter arrangement of freezing hole,reducing freezing,temperature hole protection and other aspects,put forward the protection measures of formed borehole wall,reached the good condition of borehole wall in freezing method construction.
