Application of Multi-source Information Fusion and Knowledge Discovery in Coal Mine Gas Monitoring

Aiming at coal mine gas disaster, multi-source information fusion technology is used to collect gas parameters, such as gas concentration, ventilation, coal and rock power and temperature, coal dust and other gas hazard information, gas fusion method based on fuzzy expert system is designed to predict outburst decision-making level, the credibility distribution of the outburst prediction results, which improves the ability of outburst forecasting by multi-source information fusion system.
