The value of an initial shear modulus G is essential for a safe use of objects subjected to dynamic loads. Such a situation occurs at the Żelazny Most dump where paraseismic activities are due to copper ore mining. The paper presents the results of field investigation with seismic cone SCPTU and a latest generation of seismic dilatometer SDMT, Dutch company A.P. van den Berg. The aim of the tests was to estimate the applicability of the latter through statistical analysis of results acquired from both methods. The values of constrained moduli derived from CPTU and DMT tests are also compared.
