Abstract
The project of underground electric transportation scheme for Perm city is considered. Geomechanical calculations of the proposed scheme have been performed to determine the stress-strain state around the unsupported circular opening in elastic approximation using geoinformation technologies. The calculation of the lining is performed using the method developed by B.A. Kartozia and V.N. Borisov. In conclusion, the methodology of obstruction and calculated geometric parameters of the mine support are given.
