Seituly K. Modern approaches to slope stability valuation while surface mining / K. Seituly, A. N. Shashenko, O. S. Kovrov // Наук. вісн. Нац. гірн. ун-ту. - 2014. - № 5. - С. 51-57. - Бібліогр.: 2 назв. - англ.Controlling rock massif conditions and forecasting stability of slopes and pit walls are among the most important engineering challenges for safety and efficiency of operations while surface mining. At present there are about 300 methods developed for studying geomechanical processes occurring in open pit slopes that allow predict their stability considering the impact of natural and anthropogenic factors. Purpose. Elaboration of new methodological approach regarding integrated slope stability assessment of pit walls and overburden dumps. Technique. The paper is based on the analysis of existing methods for estimation of slope stability well proven in practical applications. The general analytical solutions concerning slope stability based on hypotheses of flat and circular cylindrical sliding surface are considered. The application of slope stability nomograms based on an integrated approach to assessment of slopes with consideration of geological conditions and geometrical parameters are in detail discussed. Findings. The slope stability nomograms with dimensionless quantities obtained via numerical simulation allow us to determine geometric parameters of the rock massif nearby the slope face considering geological, hydrogeological and technological factors. Originality. As a result of multiple stages of numerical modeling of geomechanical processes in the landslide prone slopes, the values of the safety factor for the pit walls and dumps of the opencast colliery Maikubenskiy (Republic of Kazakhstan) have been calculated, which allowed us to develop the slope stability nomogram for changeable geological and mining conditions of the deposit. Practical value. Development and application of the slope stability nomograms is a useful engineering tool for quick calculating geometric parameters of rational open pit edges with regard to specific geological conditions of the deposit and controlling the state of rock massif at the quarry.
