Risk Decision Evaluation of Mine Gas Explosion Emergency Rescue Based on Vague Set

At present, coal resource mining has been regarded as the most dangerous industry in China. It is especially affected by gas explosion disasters. Its serious destructive ability, economic loss and heavy casualties have brought serious damage to the safety of coal mining in our country. This article aims to study the risk decision-making evaluation of mine gas explosion emergency rescue under the Vague set. Based on the analysis of the Vague set, the influencing factors of mine emergency rescue, the risk analysis link and the identification of mine gas explosion hazards, the risk of emergency response to gas explosion was constructed. The empirical research results show that the evaluation results are completely consistent with the evaluation objectives of the basic emergency measures, and have certain guiding significance for the prevention of gas explosions and disaster rescue in the later period.
