Quantitative Analysis on Hazard Prediction of Coal and Gas Outburst

According to interrelated theory and influence factors for coal and gas outburst, the present paper sets up an evaluation index system and also applies fuzzy synthetic access method to show the result quantificational. With an actual simple, calculation process of index value and application of fuzzy synthetic appraisal method is particularly analyzed and the results show consistent quality to the fact situation preferably. Those researches can provide some theoretic references for prevention and management of coal and gas outburst.
