Abstract
Aiming at the clean production situation of coalbed methane both at home and abroad and the lack of evaluation methods for clean production of coalbed methane in our country,a comprehensive evaluation model for clean production of coalbed methane was put forward.7 first-level indices and 24 second-level indices were selected to build an evaluation system,based on the analytic hierarchy process,the weight of each index was calculated by MATLAB program,and the index scoring standard was deternimed by referring to the production data and standards of the advanced enterprises at home and abroad; the clean production level of coalbed methane extraction was evaluated by matrix compound operation and the membership function.The evaluation model was verified by taking a coalbed methane project in Qinshui coal field as an example.The results showed that the model could objectively reflect the clean production level of the enterprise projects and promote the implementation of clean production of coalbed methane.
