Abstract：The homogeneous，layered and block surrounding rocks anchored by crossing cables were studied in two groups of modeling tests to improve the explosive resistivity of country rocks. The macroscopic failure mode，the swelled shape，the distribution of cracks and the size of the explosion cavity of both reinforced and unreinforced surrounding rocks were studied. The research results showed that the crossing cables increased the tension strength and shear strength of rock，the explosive resistivity of country rocks was improved notably. The degree of model destruction was significantly influenced by rock characteristics. For the anchored rocks，the swelled height of the block models are bigger than the ones of homogeneous and layered models. The rock characteristics are the main factors affecting the crack distribution of the models. The size of explosion cavity of the homogeneous model anchored by the crossing cable is the smallest，of the block model is medium，and of the layered rock is the biggest.
