PROBABILISTIC MODELS OF LIMIT EQUILIBRIUM AND FACE DEFORMATION DESIGNED OPEN PIT WITH DYNAMIC PARAMETERS PREDICTION OF SLIDING SURFACES USING THE METHOD OF SPECTRAL ANALYSIS OF SEISMIC PROFILING

Abstract

JSC "Giproruda" developed probabilistic models of limit equilibrium and deformation of open pii face based on methodical materials VNIMI. These patterns are formed in matrix form using the data base and embedded software MS Office Pro and matrix model of mining and transport PitDelevel. A set of procedures was developed for the automated formation of possible slip surfaces in the conditions of spatially inhomogeneous physical and mechanical properties of face rock mass and its weakening zones.
It is proposed to use the developed model of mass explosion and dynamic spectral analysis of the array in the most dangerous zones of face rock mass to reveal the localization of resonance frequencies and parameters of blocks in the zone of surfaces
sliding for regulation the order of open pit mining, parameters of drilling and blasting and transition the face in stable state.
