摘要：Aiming at the problems of large amount of engineering, long construction period and high economic cost of regional outburst prevention measures in Dongyi Mining Area of Weijiadi Coal Mine, the grey clustering fuzzy evaluation method is used to investigate four regional outburst prevention measures from five indicators of Engineering quantity, construction period, capital input, cost of gas control and prevention of secondary disasters, and the best regional outburst prevention measures are selected. The results show that the best regional outburst prevention measures are drilling strips through strata and pre-draining coal seam gas by drilling along strata in floor rock roadway, with a quantified score of 0.9179, which is greater than the quantified results of the other three regional outburst prevention measures.
