Predicting Coal Spontaneous Combustion by means of Gas Analysis Method

摘要

The exeriment on coal heating and oxidation was performed. The indicator gases predicting coal spontaneous combustion were detemined based on the law of gas released from oxidized coal with temperature rise. Reliability of indicator gases in different oxidation phase was analyzed with the aid of gray correlation analysis. According to experimental data and analyzing result, the system of predicting spontaneous combustion by means of computer was established.
