Abstract

At different times and by different authors, attempts have been made to relate the amplitude-frequency characteristics of the seismic signal to charge parameters, conditions of its detonation, and the size of the fracture produced by the explosion. To such attempts it is possible to refer results of measurement of parameters of stress waves at explosion in conditions of all-round compression, experimental and theoretical researches of speed of growth of cracks from explosion of a single charge in rocks. The dependence linking the frequency of medium oscillation with the Poisson's coefficient, longitudinal wave velocity and the maximum radius of the fracture zone is proposed.
