Abstract

In this paper, we will define the basic procedures of the concept of slope stability of the working front, the stability of the working slope ending up as a result of the presence of surface water, and how the increase in the level of suboxide water affects the values ​​of geomechanical parameters, wherein the structure of that mass of coal cover are several types of layers or different substrates of soils (clays), which it proves that there are heterogeneous lithologies in the locality of the surface coal mine "Oslomej-West" Kicevo. The following two methods have been used to analyze the general slope stability: Methods for boundary equilibrium and Numerical methods. The main components used for slope stability analysis are: Presence of surface water and level of non-toxic waters. Physico-mechanical characteristics of the soil researched in the field, in the laboratory and the safety factor (Fs). The slope stability reduction is done with the following software packages: GGU Stability, SLIDE and PLAXIS. The paper presents the assessment of slope stability with a special focus based on the different values of the porous water coefficient (ru) and the change of possible and expected values of geomechanical parameters (angle of internal friction and cohesion) that affect the value (size) of the security factor.
