摘要
为了对霍州矿区煤巷围岩稳定性进行分类,采用基于模糊等价关系的动态聚类分析法将样本巷道分为5类;选择煤巷顶板强度、底板强度等8个指标来作为分类评判指标,运用5标度的层次分析法对8个分类指标进行权重分配。以分类结果为基础,提出霍州矿区每类巷道的合理支护对策;并基于C语言编制了分类程序以便于分类计算方便、快速、准确。研究结果表明,将模糊综合聚类法和层次分析法应用于煤巷围岩稳定性分类效果良好,分类结果符合实际需求;以分类结果为基础,对每类巷道提出合理支护对策,为现场施工提供有效指导与参考。

Abstract
In order to classify the surrounding rock stability of coal roadway in Huozhou Ming Area,the atthors applied fuzzy clustering analysis method based on fuzzy
equivalence relation to divide the roadway samples into five types. Eight indicators suchas coal drift roof strength, floor strength,were chosen as classification evaluation in
dicators. The new analytic hierarchy process of five scales was put forward to distribute the weight of eight classification indexes. Based on the classification results,this st
udy put forward reasonable supporting countermeasures for each type of roadway in Huozhou Mining Area. A classification program was compiled,using C language,for the
classification calculation conveniently,rapidly and accurately. The results showed that the fuzzy clustering method and AHP was applied in coal roadway surrounding stabilit
y classification very well,and the classification result conform to the actual situation. The reasonable supporting countermeasures for each type of roadway,based on the cl
assification results,provide effective guidance and reference for site construction.
