| 摘 要： | 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。

| Abstract: | This Paper discusses the research at home and abroad into the key Parameter resulting in a rise in the temperature in mine wells , i.e. unsteady heat transfer coefficient K between surrounding rock of the mine wells or lanes and airflow,clarifys its essentiality and influencing factors.It importantly investigates the theorectical calculation formula and curve of K; and then by using a mathematically multivariable regression method of curve-fitting and a computer program, the practically approximate formula of K is obtained. Thus the difficult point is broken through that the value of K can not be compiled into computer programs in the form of function during prediction of the airflow temperature, which creates good conditions as to the computerization of the prediction of the airflow temperature in mine wells. |
