| 摘 要： | 为解决深部开采带来的热害问题,基于地质学和热力学理论,建立了热害矿井巷道温度场的数学模型,并对其进行了数值模拟分析,初步研究了巷道内部温度场随埋深的变化规律。计算结果表明,巷道温度场对埋深敏感,温度场的变化符合由快到慢的变化规律,温度随埋深的增加而呈阶段性递增,这对于矿井热害的综合治理具有重要意义。

| Abstract: | In order to solve the heat harmful problem by deep-seated exploitation, a mathematical model of temperature field of tunnel based on the theory of geology and the thermodynamics is built in heat harmful mine, and the numerical simulation analysis is studied. In the paper, it primarily studied change rule of temperature field of tunnel with burying depth. The results indicate that the temperature field is sensitive to burying depth and the temperature increased step by step with burying depth. Computational solution makes known that it is susceptible that the temperature field in tunnel is adjusted to burying depth and the alternation rule of temperature field is from slowly to quickly, at the same time, the temperature with burying depth increase presents phase increasing by degrees. This has the significant sense as to the comprehensive harness of the heat harmful mine |
