The Analysis of Heat Source and Prediction of Thermal Environment in Coal Mining Face
Abstract:The high temperature damage is the important engineering problem which the coal resource deep mining faces. This article take 9309 coal mining face in some mine as an example, through the analysis mine heat source, uses the airflow temperature forecast model, had forecast the distribution of airflow temperature in coal mining face and two cross heading channels, and has carried on the contrast with the measured results. The results indicated that combined the analysis mine heat source and airflow temperature forecast to be able to carry on the accurate forecast to the heat damage degree in coal mining face, this has the important meaning to the mine ventilation and the partial cooling design.
Keywords: High temperature mine mine sources of heat thermal environment prediction
