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,研究了巷道内部温度场随埋深和通风热速的变化规律。计算结果表明,巷道温度场对埋深的敏感度要高于风速、温度随埋深的增加而呈阶段性递增。控制入口温度是解决矿井热害的关键。以上结论为矿井热害的综合治理提供了重要依据。

关 键 词:热害矿井  温度场  原岩温度  风速  围岩

Research on distribution rule of temperature field in heat harmful mine
Abstract:In order to solve the heat\|harm problems caused by deep\|seated exploitation,a mathematical model about temperature field of tunnel in heat\|harm mine is established based on the theory of geology and thermodynamics.In the paper,it is studied that the rule of tunnel temperature field variation with burying depth and wind speed.The results indicate that sensitive degree of temperature field affected by burying depth is superior to that by wind\|speed.The temperature increased by stages in accordance with burying depth.The key of solving heat\|harm of mine is to control entrance temperature.The above conclusion provides important evidence for comprehensive management in heat\|harm mine.
Keywords:heat harmful mine  temperature field  temperature of original rock mass  wind speed
