摘要：
The in-situ experiments with the use of borehole deformometers are carried out. It is established that the response to blasting is of the marked alternating character, and approaching of explosion foci to the measurement points leads to increase in strains with nonlinear dependence on the distance. The dimensions of geoblocks involved in the deformation processes and the velocity of their movement are determined.
