深井巷道围岩地温场温度分布可视化模拟研究

Visualization simulation of temperature distributions in geothermal field of surrounding rock of deep mine tunnels

根据地温场温度分布的数学模型,应用有限元法模拟了深井巷道围岩地温场中4种常见隧道断面的岩石温度分布特征规律,揭示出地温场内温度分布和地热学参数及时间、空间之间的本质关系,实现地温场内温度分布的二维动态等值线表征,直观地再现了地温场内温度分布非稳态变化的动态过程。

Based on the mathematical model for rock temperature distribution in a geothermal field,the properties of rock temperature distribution in geothermal field for four kinds of surrounding rock cross-sections of deep mine tunnels,has been simulated by using finite element method.It is shown that the relationship for rock temperature distribution varied with the geothermal parameters,time and space.Namely,2-dimensional time-dependent isograms clearly showed the process for rock temperature variation and distribution in a geothermal field which has been redisplayed with visualization numerical simulation.
