高温矿井风流温度和湿度预测及其程序编制

The program of predicting temperature and humidity in deep coalmine

分析了不同外界条件下巷道围岩与风流的不稳定换热系数的理论计算方法。讨论了存在不同壁面粗糙程度的巷道中围岩或煤壁氧化散热及其对风流温度的影响。然后以热力学中热质交换理论为基础,建立了单风路矿井巷道沿程风流温度、湿度的预测计算的理论以及数学模型,并编制了井下巷道风温分段计算的计算机程序。最后将该计算机程序应用于实际现场中,得到的计算结果与实测结果吻合,检验了该计算机程序的可靠性。

This paper analysis the theories calculation method of unsteady heat change coefficient in different Environment. Discuss the factor Influence to the temperature in tunnel, such as heat calories from wall Oxidized in different rough degree On the foundation that hot and quality exchanges in thermodynamics, establish to the mathematics model of the system of predict mineral temperature and degree of humidity. Mean time, procedure the computer program. At last, Apply the computer program to Sanhejian Coalmine and receive good results.
