建立了反映跨采巷道具体稳定状态的围岩结构稳定性指标，以实测资料为样本确定出指标权值，采用模糊ＩＳＯＤＡＴＡ 聚类分析方法得到结构稳定性亚分类模式，提供了结构稳定性实用分类方案，可应用于跨采巷道稳定性预测与支护设计。
The stability index of surrounding rock is established to reflect the concrete stable condition of cross-mining roadway. The measured data are used as the sample to determine the index weight. The fuzzy ISODATA cluster analysis method is used to obtain the sub-classification mode of structural stability, which provides the practical classification of structural stability Program, can be applied to the stability prediction and support design of cross-mining roadway.
