In work the basic features geomechanical processes of rocks occurring in a file are stated at tunneling and developments of underground constructions. Principles of the organisation mathematical modelling of processes displacement and deformations of rocks for an estimation of harmful influence of underground building on buildings and constructions are resulted. The basic lacks of known approaches to modelling of geomechanical processes are stated, recommendations about the decision of key problems of calculation displacement in a pedigree file are made. The basic results of application of the complex approach to a look-ahead estimation displacement and deformations at maintenance of building of city underground constructions in St.-Petersburg are presented.
