Some equations for obtaining the temperature of air at longwall face have been published, but they are unpractical because the heat in the gob which flows into the face and influences the temperature most significantly, has not been considered.
The 76 measured examples of the temperature of air at face in Miike and A. H. IIIEP5AHB's analytical equation for theoretical temperature that treats time factor most appropriately in the published equations, were used in order to put the equation to more practical use.
As a result of investigating many data, an experimental equation was set up to obtain the temperature raised by the heat flow from the gob.
According to the method described in this report, it becomes possible to forecast the temperature practically at the end of face including the heat from the gob. And it is also possible to make clear the problems of temperature rise theoretically and practicable to come into operation an effective measures for high temperature.
