Theoretical basics and scientific and technical principles for justification, calculation and constructions security and their fixing means application using bearing capacity of in-circuit rock mass, its geomechanical state changing and deformational and forth characteristics of the system: “fixing – rock mass” have been developed.

Integrated geomechanical concept of mining stability problem solving, based on positions of system and process analysis at defining of the structure: “fixing (security construction) – rock mass” as the local geomechanical system by means of control deformation and forth parameters of constructions security.
