The stage is focuses on the creation and development of analytical methods of solution of spatial and flat mixed problems of the theory of elasticity and plasticity, allowing to investigate of the stress-strain state the rock mass at underground development stratal of mineral deposits. With the help of the integral Hankel transform obtained the analytical solution of the axisymmetric problem about the deformation of an isotropic half-space under the load, distributed over a circular area, in the case when out of area efforts, border elastically is fixed. Investigated elastoplastic balance of isotropic the plane with two identical circular holes for exponential the condition of plasticity, when the plane is compressed by uniform efforts along and across the line, connecting the centers of the cutouts. Using the method of characteristics are investigated numerically the distribution of stresses and displacements in an anisotropic plastic half-strip, compressible rigid plates. On the basis of solving inverse problem of the theory of a filtration are made computer calculations of formation pressures and filtration coefficients of the two gas-bearing layers, uncovered through one well, the numerical results are analyzed for different measurement options wellhead pressure.
