From geological point of view tailings dam materials are different compared to regular types of soil. In mechanical aspects it is material that has regular mechanical properties like shear parameters and deformation moduli. Based on the huge expansion of the hardening soil model in the last 20 years, this paper discusses the E50 modulus and its relation to some of the well-known physical soil properties. Expressions of E50 in respect to water content, grain size distribution, void ration, site depth and confining pressure are introduced. Some data are analyzed and weak correlations are obtained. All the E50 modulus values are obtained of both undrained and drained triaxial tests on the tailings dam material samples taken from the Bulgaria biggest tailings dam. Regardless of its variability and the high standard deviation values, there were enough data to define at least the tendency for the E50 dependences on the tailings dam material properties. Remarks and suggestions in respect to the usage and compliance of the results are made.
