The article presents the main results of theoretical and experimental research in the field of non-destructive testing and forecasting of geomechanical condition of the arched part of the transport tunnels. It has been shown that this goal can be to apply a method of acoustic resonance inspection. Methodology Research was registering the resonant response of the layered rock mass to impact mechanical excitation of an acoustic signal. Initiation and receive elastic vibrations produced in the lower layer of the breed. These technical and economic parameters allow to recommend Geophysical prediction described underground geophysical methods for wide industrial use during transport tunnels
