Abstract

The subject of this paper is the analysis of the
geo-mechanical stability of slopes of the surface coal mines of the main
geometry factors. Its main purpose is to define the interaction between the
geological environment and the engineering activity. Therefore, in solving
this problem all available documents from the previous researches and
examinations for obtaining more credible and relevant data are used. Because of
the above mentioned, the thesis shall obtain the following analyses: Description
of the existing situation from geological aspect; Application of various
numeric and graphical methods; Selection of most optimal geomethric parameters
and stability analysis; In general, various methods are used for slope
stability analysis. They can roughly be divided into two groups, such as:
Border balance methods. In general, the slope stability analysis consists of
the following components: Safety Factor Fs; Slope – Geometrical properties; Physical-mechanical
properties of tested soil materials; Groundwater. The stability calculation
shall be conducted by various methods with the software packages GGU Stability
(BISHOP, JANBU). Discovering the right measure and the exact ratio between the
advantage and the limitations of a given method is possible only through
appropriate methodological approach, where aspects relevant to specific
problems in geotechnical engineering shall be analyzed. Following significant
results occurred from the work on this doctoral dissertation: 1) Analysis and
sensitivity evaluation of the safety factor in the change of the values of
certain geo-mechanical parameters. 2) Critical review of the selection of
methods for geo-mechanical stability analysis;

Keywords
