摘　　要：矿山开采水平的不断纵深发展使矿井井下的工作环境恶化,文中为研究进风井筒风流温度的变化规律,将实测数据的数理统计回归法和差分法结合了起来,是研究进风井通风流温度变化规律的一种新的实用方法,对研究进风井筒风温变化规律起到了理论指导的意义。The increasingly further development of mine exploitation level has deteriorated the working conditions of underground mining. The research into changing laws of wind temperature is regarded as the important basis of air conditioning design of mine and its economic value. In this article, the changing laws of wind temperature in intake shaft are studied. Combining the mathematical statistics regression method of actual measured data with the difference method is a new practical approach to research into the changing laws of wind temperature in intake shaft. It has theoretical guiding meaning for research on the changing laws of wind temperature in intake shaft.

关 键 词：进风井筒 风温变化规律 实测回归法 差分法
