Abstract:

When ordinary method changes in freezing method in coal mine construction, antifreeze protection measures must be taken for the forming wall in common construction method. The effective method is the temperature control hole controlling the development of freezing front, but there are no specifications and theoretical supports for the temperature control hole design in protection of the forming wall. With the help of the finite element numerical simulation software-ANSYS, the article has done a preliminary study about design of the temperature control hole in Tashidian air shaft construction, and summarizes the design method.

Key words: Protection of Forming Wall, Temperature Control Hole, Heat Flux Density
