Abstract
This paper takes the comprehensive evaluation of coal mine gas control mode as the research target to construct a multi-factor and multi-index gas control mode evaluation system with 4 factors and 16 evaluation indices. The analytic hierarchy process (AHP) is used to determine the weight of gas control evaluation indices, and to construct a fuzzy comprehensive assessment model (FCAM). The study finds that the total ranking of various factors in the gas control mode can basically meet the consistency requirement; it should ensure that the wind flow in the mine roadway is sufficient and stable, the professional quality of the operators is excellent, and the production system is perfect, so as to achieve comprehensive improvement of gas control effect; when evaluating the gas control mode, the evaluation factor set and the result evaluation set are combined, the evaluation results are represented by a fuzzy set, and the evaluation matrix T is obtained. Finally, a corresponding evaluation model is established combining the weight vector W.
