Abstract
The article gives specifications and design features of a new-generation portable digital geoacoustic instrument for local geomechanical control. Field application of the instrument in rockburst-hazardous conditions is described and its capacity of efficient express-estimation of deformation processes running in the periphery of a rock mass is illustrated.
