SPONTANEOUS COMBUSTION PREDICTION METHOD FOR COAL

摘要

This spontaneous combustion prediction method for coal is for predicting the spontaneous combustion of coal which forms a pile (layers of coal in a coal storage facility). This spontaneous combustion prediction method includes a physical property value determination step for determining the physical property values of coal, and a temperature distribution prediction value determining step. In the temperature distribution prediction value determining step, on the basis of the physical property values determined in the physical property value determining step, a temperature distribution prediction value which is a prediction value of the change over time of the temperature distribution in the pile is determined by analysis. According to this method, the time when the coal reaches a spontaneous combustion temperature, and the location of such coal, can be predicted without the need to construct an actual pile.
