Safe management of tailings storage facilities requires evaluation of embankment stability dams. In case of dams constructed by upstream method, special attention is drawn to evaluation of liquefaction potential. This requires evaluation of state of saturated, not compacted tailings material containing various amount of fines. Conventional methods based on static or dynamic sounding and standard sampling can?t assure required accuracy in determination of void ratio of deposited material. The paper presents results of shear wave velocity measurement utilized for evaluation of in situ state of tailings material containing various amount of fines. Advanced triaxial tests carried out on representative batches of tailings are used to establish basic correlation between shear wave velocity and soil state including contribution of void ratio and state of stress. Application of hybrid method, based on laboratory and field measurement of shear wave velocity shows an effect of a projection of correlation developed based on triaxial tests on in situ tailings profile.
