通过层次分析法(AHP)构建首采区拉沟位置方案评价指标体系层次结构模型,确定各影响因素的权重。结合模糊数学(Fuzzy Mathematics)进行模糊综合评价,求得模糊综合评价向量,根据最大隶属度原则选择首采区拉沟位置。
Through the Analytic Hierarchy Process (AHP), the hierarchical structure model of the evaluation index system of ravine location scheme in the first mining area was constructed, and the weight of each influencing factor was determined. Combining with fuzzy mathematics, fuzzy comprehensive evaluation is carried out to obtain fuzzy comprehensive evaluation vector. According to the principle of maximum membership degree, the position of pullout groove in the first mining area is selected.
