Abstract:
In order to scientifically and rationally evaluate the actual effect of coalbed methane utilization model in Yangquan Mining Area, 4 first-level indexes and 10 second-level indexes are selected to construct the comprehensive evaluation index system of coalbed methane utilization model. A method for evaluating the effect of coalbed methane utilization model by combining analytic hierarchy process(AHP) with fuzzy comprehensive evaluation is proposed. The weight matrix of evaluation target is constructed by AHP, the weight of each index is calculated by MATLAB program, the scoring standard of index is determined based on the actual situation, the membership function is set up by fuzzy evaluation method, and then the actual effect of coalbed methane utilization model is evaluated by matrix compound operation, and different grades of quantitative evaluation are given, including “general”, “better”, “good” and “very good”. Taking the coalbed methane utilization technology being used in Yangquan Mining Area as the evaluation object, the evaluation model is tested. The research results show that the model objectively reflects the actual effect of coalbed methane utilization model, and points out the next optimization direction of coalbed methane utilization model in Yangquan Mining Area.
