为了建立科学的巷道支护方案评价体系,综合考虑影响巷道支护的众多因素对各评价因素指标进行分级,采用相对重要程度相关等级计算法确定巷道支护方案各评价因素的权重,利用基于优势关系的粗糙集理论对巷道支护方案建立评价体系,对条件属性进行属性约简,生成最少偏好决策规则集,并应用灰色关联理论对约简后的各条件属性重要程度进行分析,不仅评价优选巷道支护方案,而且对各因素之间的内在关系进行分析。应用模型对某铅锌矿的支护方案评价体系分析,结果表明:该模型对巷道支护工作具有一定的指导意义。
In order to establish a scientific evaluation system of roadway support scheme,many influencing factors of laneway surrounding rock were comprehensively considered and graded,then the relative importance of relevant rank calculation method was applied to determine the weights of evaluation factors to soft failure roadway in high ground stress scheme.The rough sets were applied to establish laneway support scheme evaluation system based on the dominance relation,condition attribute was reducted,preferences decision rules was generated,and grey correlation theory was applied to analyze importance of each reducted condition attribution,the optimum scheme of laneway support was evaluated and selected,and the inner relationship between various factors was analyzed.Some supporting program of a certain lead-zinc ore was evaluated with this new model,and the results show that the model has directive significance to roadway support.
