【Abstract】 The structural stability indexes reflecting the concrete stable conditions of surrounding rocks of gallery influenced by overhead mining are set up and their weights are determined from field measurement data. A sub classification pattern of the structural stability is obtained by using ISODATA fuzzy cluster analysis method. A practical scheme of stractural stability classification is also put forward. It can be used in stability prediction and support design of gallery influenced by overhead mining.更多还原
