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。 In order to solve the problem of thermal damage caused by deep mining, a mathematical model of temperature field in the heat-affected mine roadway was established based on the theory of geology and thermodynamics. Numerical simulation analysis was conducted on the temperature field of the mine, The law of change. The calculation results show that the temperature field of the roadway is sensitive to the buried depth, and the change of the temperature field accords with the changing law from fast to slow. The temperature increases step by step with the increase of the buried depth, which is of great significance for the comprehensive treatment of thermal damage in the mine.
