Obtained an analytical solution of the mixed elasticity theory problem for a transversely isotropic strip with a free from external efforts the upper boundary in the case when the lower boundary is elastically fixed on out end-sections appended acting on the elastic body distribution of the normal load. Formulas are given for the components of the stress tensor and the displacement vector in the elastic strip. Poposed method for solving axisymmetric mixed problem for a transversely isotropic elastic half-space with a fixed boundary under the action of an elastic body of the normal load, uniformly distributed in a circular area. Based on the analytical solutions developed algorithms calculation of stresses and displacements at arbitrary points of a transversely isotropic half-space. Implemented the calculations of stresses and displacements in planes parallel to the boundary of the half-space. Investigated distribution stress in rocks of the soil сleaning-mines, conducted in an anisotropic rock mass. Established the influence of mining and geological conditions, the anisotropic properties of rocks and technological measures on the formation of zones of tensile and compressive stresses in the vicinity of working face at underground coal mining.
