Abstract
In the given work the way of an estimation geomechanical effect of additional activization of deformation process in a file of rocks and on a terrestrial surface is stated at a construction of two and more parallel tunnels on the basis theoretical decisions of mechanics the continuous environment. Similar quantitative and quality standard of this effect at calculations stress has received a wide circulation in mechanics of underground constructions and other applied areas. In mine surveying calculations displacement and deformations mainly empirical approaches are traditionally used. The resulted decisions allow to carry out such estimations and to take into account similar geomechanical effects in calculations of displacement and deformations.
