Experimental Study on Physical and Mechanical Properties of Iron Tailing Materials

摘要: The physical and mechanical properties of tailing materials are important for the design construction tailings dams. In present study, laboratory experiments were performed to investigate geotechnical two different iron (coarse fine). Compared coarse tailings, fine showed greater coefficients compressibility smaller permeability, shear strength. With decrease in void ratio, oedometric modulus increased permeability decreased. relationships between ratio coefficient compressibility, as well hydraulic conductivity, can be fitted with logarithmic functions. Moreover, we found consolidation Cv gradually both during compression process. strength measured though direct tests triaxial tests. results friction angle cohesion obtained from test methods accordance each other. This study provided useful information understand behaviors mine fundamental data scientific safety evaluation
