| Abstract: | This paper describes the distribution of structural alteration shear zone in mining area, and revealed some ductile deformation characteristics. Mechanical analysis of the ductile shear zones is done in two ways. It also describes the features of specific structure in the shear zone, and briefly expounds the zonation of the shear zone. The reason for the formation of ductile shear zone in mining areas is analyzed too. |
