摘　　要：针对跨采巷道的矿山压力特点，建立了反映巷道具体稳定性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聚类分析方法得到跨采巷道结构稳定性分类模式，提供了跨采巷道结构稳定性实用分类与锚杆支护参数设计的实用方法，可应用于跨采巷道稳定性预测与锚杆支护设计。In accordance with the characteristics of ground pressure arround roadway that is affected by overhead mining and proceeding, structural stability indexes that reflect the concrete stable conditions of surrounding rocks are set up, the weight of each index is determined by using field measured data as samples. The structural stability classification pattern of roadways affected by overhead mining is obtained by applying ISODATA fuzzy cluster analysis method. Also a practical method of structural stability classification and bolt support parameters design is put forward. It can be used in stability prediction and bolt support design of roadways affected by overhead mining.
