Comprehensive evaluation method of coal mine gas utilization and emission reduction

According to the actual status of coal mine gas utilization and emission reduction in China, and on the consideration of the policy, technology and results of utilization and emission reduction, we established the comprehensive evaluation method of coal mine gas utilization and emission reduction by Analytic Hierarchy Process. We used this method to assess the capacity of gas utilization and emission reduction in Luling Coal Mine, and the results of evaluation show that the capacity of gas utilization and emission reduction in Luling Coal Mine is outstanding, and this result is consistent with the result of National Coal Mine Gas Control Expert Consultation of China in 2010, which verify the reliability of this evaluation method.
