SPONTANEOUS COMBUSTION PREDICTION METHOD FOR COAL

摘要

coal-ignition prediction method of the present invention is a way to predict the spontaneous combustion of coal that make up the file (within the coal seam coal storage facility). Autoignition prediction method of the present invention, has the physical property determining step for determining the physical properties of the coal, the temperature distribution of the predicted value determination step. Temperature distribution predicted value determining step is based on a physical property determined by the physical property determining step, the step of determining the predicted value of the predicted value of the temperature distribution changes over time in the temperature distribution in the file by the analysis. According to the method of the present invention, it can be predicted when and where the coal reaches the ignition temperature, without the need to build the real file.
