摘要：
A method is proposed for estimating the stress state of rock mass composed of two rock layers with different deformation properties around of the excavation with an arbitrary cross-section. The method is based on an analytical solution of the elasticity theory problem obtained using the theory of functions of a complex variable. The influence of the rock interface on the stress state of the rock mass and the stability of the vaulted mining is investigated. For different positions of the interface, the stress distribution in the rock mass is obtained and conditional zones of inelastic deformations are determined.
