Abstract
The authors offer an approach to estimating deformation of rock mass around a stope (zonal disintegration) at deep levels. The algorithm of geomechanical condition of rocks is developed, and the ranges of stresses and strains in the zone of influence of a stope are identified. It is shown that when Young modulus in the vicinity of the stope is higher than inside the rock mass, displacements of the stope perimeter are lesser.
