The analytical solutions of the mixed problems about the deformation of elastic half-space and transversally-isotropic half-plane lying on the perforated elastic base are received. The boundaries of application of a perturbation method at the decision of elastic-plastic problems for a plane with hole are established. Distribution of stresses in a rock massif at the extracting of coal seam with changing thickness is investigated. Problems of a filtration theory for two gas-bearing beds, which opened with one well, at variable hyper compression factor are considered Product Description popup.authors popup.nrat_date 2020-04-02 Close
