Abstract In order to improve the efficiency of classification of rock mass blastability, a method for classification of rock mass blastability based on concept lattice and rough set was proposed. Four control factors of rock mass blastability, i.e. specific gravity, static tensile strength, integrity coefficient of rock mass, and dynamic strength under impact, were selected as the evaluation indexes. The concept lattice was used to analyze and reduced the index, and two irreducible indexes of specific gravity and dynamic strength under impact were obtained, then the rules of classification of rock mass blastability were generate through rough set. The rules of classification of rock mass blastability were applied to the classification of rock mass blastability in Nanfen open pit iron mine, and compared with the other three classification methods. The results show that the classification results using method for classification of rock mass blastability based on concept lattice and rough set in accordance with which from the other classification methods. This method reduces the classification index, and does not need to determine the index weight. It improves the efficiency of classification of rock mass blastability.
