【摘要】 以山西省峁底矿为例,基于层次分析法进行权重计算,对模糊综合评价法进行改进,引入有效度、量化向量以及置信度准则对传统地质环境评价方法评价结果进行修正。结果表明:传统模糊综合评价模型评价结果为地质环境质量Ⅰ级(一般),有效度为0.121 89;改进模糊综合评价模型k0=2时,隶属度为0.775 4(置信度>0.65),矿山地质环境质量修正为Ⅱ级(较严重)。分析认为,改进模糊综合评价方法更适用于矿山地质环境质量评价。更多还原

【Abstract】 Taking Maodi Coal Mine in Shanxi as an example,the weight calculation was carried out based on Analytical Hierarchy Process( AHP),and the fuzzy comprehensive evaluation method was improved. The validity,quantization vector and confidence criterion were introduced to modify the evaluation results of traditional geo environmental assessment methods. The results show that the evaluation result of traditional fuzzy comprehensive evaluation model is grade I( general) with a validity of0.121 89. When k0 of the improved fuzzy comprehensive evaluation model is 2 and the membership degree is 0. 775 4( confidence > 0. 65),the mine geological environment quality is revised to grade II( more serious). The analysis shows that the improved fuzzy comprehensive evaluation method is more suitable for mine geological environment quality evaluation.更多还原
