本文讨论了国内外对影响矿井温升的关键参数——井巷围岩与风流间不稳定换热系数K值的研究,阐明其本质及影响因素,着重探讨了K值的理论计算公式、理论曲线;并用曲线拟合多元回归的数学方法,采用电算程序求得了K值实用近似计算公式,突破了风温预测计算中K值没能以函数形式编入电算程序的难点,从而为井下风温预测电算化创造了良好条件。
This paper discusses the domestic and foreign research on the key parameters that affect the temperature rise in mine - the study of the unstable heat transfer coefficient K between the surrounding rock and the wind flow, clarifies its essence and influencing factors, and emphatically discusses the theoretical calculation formula of K value, Curve and curve fitting multivariate regression mathematic method, the use of computer program calculated K practical approximation formula, breaking the wind temperature prediction calculation K values can not be programmed into the function of the computer program difficult, so as to the underground Computerized temperature forecast created a good condition.
