ABSTRACT: This paper presents results which concern regularities of propagation of
discontinuous zones from mined-out space in rock massif with inclined bedding
structure. The dependencies of maximal height of these zones from the
inclination angle of productive beds were found. The mechanical model of rock
massif was chosen as viscoelastic and transversely isotropic. Finite element
method was used for calculation performing. Coulumb-Mohr and maximal elongation
criteria were used for determination of discontinuous zones.
