ABSTRACT

This paper deals with the slopes, which are generated and incurred by mining of the coal
substance Doly Nastup Tusimice. Localization problem concerns open mine Libous
which is created and will run several kilometers working face front. Mining process of
open mine Libous is limited by number of technical and technological problems. One
issue is the obligation of the Plan submission opening, preparation and extraction in the
mining area Tusimice (POPD). In relation to the present POPD is needed to assess the
general stability of the slopes and sub-degree slopes in the configuration in which are
set out in POPD. The aim of this paper was to perform stability analysis of slopes in the
area considered Libous. Stability analysis of the slopes Libous was performed by force
equilibrium methods and mathematical modeling of general stability of the slopes and
their sub-levels using models that address the course of the stress function defined
throughout the rock body. As requested by the contracting authority and contractors
equipment and software used methodology was the task performed by numerical
programming system PLAXIS Professional Version 8.2 with expandable to 3D spatial
model.

Keywords: mathematical modeling, slope stability, finite slopes, mining areas
