This article take 9309 coal mining face in some mine as an example, through the analysis mine heat source, uses the airflow temperature forecast model, had forecast the distribution of airflow temperature in coal mining face and two cross heading channels, and has carried on the contrast with the measured results.

本文以某矿9309工作面为例，通过分析矿井热源，利用工作面风温预测模型，预测了工作面和两顺槽的风温分布，并与实测结果进行了对比，结果表明热源分析结合风温预测能对工作面的热害程度进行准确预测，这对于矿井通风设计及局部降温设计具有重要意义。
