The purpose of work is development of a defectoscope for nondestructive identification of spaces in rock mass on border with a concrete timbering. The principle of operation of the device consists in the analysis of parameters of vibration of a timbering after drawing blow to it. The difference from the known developments consists in contactless reception of an acoustic signal with use of the microphone. Parameters of vibration of a timbering are determined under various conditions of its contact with rock mass. Initial requirements for development of a defectoscope are experimentally defined. Its block diagram is submitted and principal specifications are given. Data on approbation of the equipment in hydraulic engineering constructions are given.
