Abstract: In view of the uncertain relationships among indexes and buildings damage in mining-induced damage predicting,and combining with the characteristics of correlation analysis,fishbone diagram,and SVM,the analysis model for mining-induced buildings damage was established.Correlation analysis theory and fishbone diagram were used to analyze the correlations,and calculate the indexes′ weights.The SVM model were trained and tested by a series of data from observations of mining-induced and damage degree of buildings,and the test results was good.The results show that the fishbone diagram can obtain the relationships between indexes and buildings′ damage,and the importance of the quantified index；The building′s own conditions including its position in Gob and building conditions are more important than others obviously,and increasing the construction of building foundation can well improve the destruction resistance of buildings；SVM model based on fishbone diagram can better consider the effect of each index on damage degree induced by mining-induced,and get a lower ratio of mis-discrimination.
