Inverse Arithmetic of the Equivalent Heat Transfer Coefficient of Mine Goaf
In order to calculate the dissipating capacity of heat sources and improve the veracity of airflow temperature forecast of mine, the equivalent heat transfer coefficient of mine goaf was calculated by means of inverse arithmetic based on the law of conservation of momentum and measured data from a high temperature working face. The results of calculation show that the equivalent heat transfer coefficient of mine goaf can reflect the heat dissipating characteristics generally and reduce the calculating method of the heat dissipating capacity of mine goaf, then it can be used better in the airflow temperature forecast.
