| Abstract: | The solution of the mixed problem of the theory of elasticity for a half plane modeling the stress-strain state of an anisotropic rock mass during the excavation of a seam is constructed. The results of numerical investigation of the length of the neardrift plastic zone of the seam being excavated as a function of the anisotropy of its plastic properties are given. Diagrams showing the stress distribution in the mass are presented.Translated from Teoreticheskaya i Prikladnaya Mekhanika, No. 18, pp. 38–43, 1987. |
