冻结停机后已成型井壁防冻研究

Research on antifreeze of the molded wall after the frozen station stopped

利用有限元数值模拟软件ANSYS研究了风速与空气温度对塔什店矿区一号井风井冻结停冻后井壁外缘影响,分析了延长温控孔开启对井壁外缘温度的作用,得出了延长温控孔运转时间能有效控制井壁冻害这一结论。

This paper the influence of wind speed and air temperature to casing outer edge of No. 1 casing antifreeze after freezing shutdown of Tashendian mine using finite element numerical simulation software ANSYS, analyzed the role extended temperature control hole to casing outer edge temperature, gained the conclusion extend running time of temperature control holes could effectively control the casing freezing.
