Abstract
The “Brod-Gneotino” coal deposit is located on south-west of the Republic of North Macedonia, near the city of
Bitola and about 10 km south of the deposit "Suvodol". According to the engineering - geological
regionalization of the terrain, the rock masses in the deposit are grouped in the part of the various lythogenetic units, or it is characterized by the presence of several engineering-geological groups of rock masses. Based on the overall performed investigations and explorations, statistical analysis was made on the results of the physical - mechanical examinations and were obtained calculation values necessary for designing of the slope stability. The calculation of the stability is according the method of Bishop (with the software SLIDE 7.0), method that is based on the conditions of boundary equilibrium. Safety coefficients are adopted according the "Rulebook on Technical Norms for Surface Exploitation of deposits of Mineral Raw Materials for slope stability on open pit and Landfills", with Fs t 1.1 for local working unburdened slopes, Fs t 1.15 for system of working slopes and burdened working slopes and Fs t 1.3 for final slopes.
