摘要
普通凿井施工遇到施工困难转入冻结凿井施工,在采用温控孔保护已成型井壁措施中,温控孔的设计没有规范和理论支撑。借助有限元数值模拟软件-ANSYS针对温控孔的设计进行了初步研究,总结温控孔设计方法。
When ordinary method changes in freezing method in coal mine construction,there are no specifications and theoretical supports for thermostat hole design in thermostat hole measures to protect the formed wall.With the help of the finite element numerical simulation software-ANSYS,have done a preliminary study about thermostat hole design in Tashidian return air shaft construction,and summarizes the thermostat hole design method.
