The mathematical model of the laminated massif designed, permitting to investigate process of a floor heaving. Parameters of a band of inelastic deformations from extent of inhomogeneity of a massif and magnitude heave are established. The model of a fissure on basis of a finite element method is designed. Laws of failure impact on a stability of an extended working are established. The algorithm of mathematical modeling of a massif with heterogeneities of a different level designed. Dependence of displacements of a contour of a working on a variation of values of a coefficient of elasticity and a Poisson's ratio is investigated. Ways of the registration of mechanical parameters of rocks in Simulink-model of a discretic three-dimensional massif of the arbitrary shape and structure are designed.
