The results of solving the problems of the stress-strain state of peripheral rock in the vicinity of the meeting point of two workings of intersection and branching type are presented. Values of the load coefficients are obtained, as well as values of the dimensions of the zone of influence of the meeting point and the conventional zone of inelastic deformations. Intersection and branching of workings at various angles are considered.
