SPONTANEOUS COMBUSTION PREDICTION METHOD FOR COAL

摘要

The coal spontaneous ignition prediction method of the present invention is a method for predicting spontaneous combustion of coal constituting a pile (coal layer in a coal storage facility). The spontaneous ignition prediction method of the present invention has a property value determination step of determining the physical property value of coal and a temperature distribution predicted value determination step. The temperature distribution predicted value determination step is a step of determining, by analysis, a temperature distribution predicted value that is a predicted value of a change over time of the temperature distribution in the file, based on the physical property value determined in the property value determination step. According to the method of the present invention, it is possible to predict when coal reaches a spontaneous firing temperature and its position without having to file a file of the real.
