SUBSTANTIATION OF OPEN PIT BOARD PARAMETERS WITH REVERSE SHARING LAYER
The deformation of the sides of quarries with reverse steeply falling layering begins long before the onset of the limiting state and is manifested in the form of opening cracks and the formation of “reverse steps ” on the surface of the slope. Moreover, the loss of stability of the side, as a rule, is not observed, but normal exploitation of the quarry is impossible. Therefore, the assessment of the stability of slopes for these conditions must be carried out simultaneously according to the bearing capacity and deformations. Based on the analysis and interpretation of the results of physical modeling, calculations by the methods of limit equilibrium and finite elements, a method for determining the limit parameters of quarry sides taking into account the strength properties of the massif is developed rocks and allowable displacement.
