摘要: 为了科学合理评价阳泉矿区煤层气利用模式的实际效果,选取了4个一级指标和10个二级指标,构建了煤层气利用模式综合评价指标体系,提出层次分析法与模糊综合评价相结合的煤层气利用模式效果评价方法。使用层次分析法构造评价目标的权重矩阵,通过MATLAB程序计算各指标权重;结合实际情况确定指标评分标准,基于模糊评判法构建隶属度函数,通过矩阵复合运算结果来评价煤层气利用模式的实际效果,做出一般、较好、好、非常好的定量评价。以阳泉矿区实际投入使用的煤层气利用技术为评价对象,对评价模型进行检验。研究结果表明:模型客观反映了煤层气利用模式的实际效果,为阳泉矿区煤层气利用模式下一步优化指明了方向。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.
