%X 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.
