Spontaneous Combustion Prediction and Combustion Regime Analysis Basing on Experiments by Gas Ratio

It has been widely used to predict the spontaneous combustion in coalmines and it helps to improve the accuracy of prediction greatly because of their special characters such as unicity, regularity and sensibility. The indicator gases predicting coal spontaneous combustion are determined based on the law of gas released from oxidizing coal with temperature, and 4 judgment criteria are put forward for the combustion regime analysis, by them they can be used as auxiliary index for the spontaneous combustion prediction too. Combined with other indicator gases, it can help to improve the accuracy of prediction greatly and is helpful to the mine fire combat and protection.
