矿井风流温度预测及热交换机理分析

Temperature Forecast to Mine Airflow and Analysis on Mechanism of Heat Exchange

为探讨矿井风流热交换机理,采用归纳法对我国部分具有高温热害矿井的相关资料进行分析研究,总结出矿井中不同地点的风流热交换规律,进而提出矿井风流热力计算的数学方法和参数选取的条件和范围。研究表明:风流通过井筒、矿内巷道和回采工作面时,其热力变化规律有显著不同。这为实施矿井降温措施,改善井下作业条件,提高矿工劳动效率和安全保障提供了理论依据。

To explore the mechanism of mine airflow heat exchange, parts of high temperature mines damaging with hyperthermia in China by induction methods are analyzed, summing up the law of airflow heat exchange, putting forward the mathematic methods of thermal design to the mine airflow, the conditions and bound to choose the parameters are put forward. The investigations show that the law of mine airflow thermal changing is different when it gets across the shaft, drift and extracting face. The investigations provide some academic gist to actualize the measure to cool down the mine, improve the conditions of underground operation, improve the efficiency of miner＇ s work.
