Czynniki wpływające na parametry wytrzymałości na ścinanie w strefach zagrożeń osuwiskowych na przykładzie odkrywek węgla brunatnego

The recently observed development into possibilities of calculation programs for calculations of stability and numerous results of laboratory investigations help to obtain a more and more perfect simulation of rockmass behaviour. Nevertheless, a problem of landslides has not been fully solved as they still originate. The analysis of slope stability requires consideration of a number of factors connected with a degree of complexity of geological structure and parameters of soils. One of the most essential problems is still a choice of reliable calculating parameters, especially in the zones of complicated geological structure. In the paper factors influencing shear strength parameters in the zones of landslide threats have been discussed while basing on the results of investigations and observations in the brown coal mines »Turów« and »Bełchatów«. Mass movements of soils in open pit mines due to their exploitation, outcrop of slops, current monitoring and technical possibilities of mines help to observe in a relatively easy way certain phenomena accompanying the processes occurring on the surfaces of a landslides. There exists a possibility of applying some results for the evolution of slope stability also in the places where observations of phenomena occurring on the slide surfaces are considerably more complicated, e.g. in the Carpathian landslides.

Powierzchnie strukturalne w górotworze złóż węgla brunatnego, ich charakterystyka i właściwości fizyko-mechaniczne
(2007) Kaczmarczyk, Robert; Rybicki, Stanisław
Field observations of geological profile of the overburden soils of lignite deposits Turów and Bełchatów shows some structural surfaces used as a slip surfaces of many landslides. They are usually surfaces of loosing structure of soil came to the existance after sedimentary, tectonic and erosion processes. In the article types of these surfaces, their structural character and some geotechnical properties are described.
