| Description
| - This paper deals with the evaluation of laboratory tests of materials from the internal dump of the coal mine Bílina, localized in the northern part of the Czech Republic. Reliable determination of the properties of the dump materials is the basis for the objective and reliable behavioural analysis of the dump Bílina and of the dump increasing process prognosis. It is expected that around the end of the mining activity (around 2035) the final height of the dump will reach about 220m. So, finally, the dump Bílina will be one of the highest dumps in the world. Any dump instability may lead to a widespread threat to people, property damage and, in the end, to the problem with the operation of the whole mine; therefore, from this point of view an intensive research is needed in this area. The paper presents the results of both direct shear box test and oedometer test of the dump material, which was classified immediately after extraction, as claystone. On the basis of direct shear test the Mohr envelopes of shear strength, corresponding to the peak and residual strength parameters (cohesion and friction angle), were evaluated for the various soil moisture. Based on the oedometer test the Young´s modulus of dump material was obtained. In addition the results of unconsolidated undrained triaxial tests for the determination of total shear strength characteristics are presented.
