Summary An investigation of stress waves near an explosive source in a gravelsandy medium has been carried out. Records of these waves obtained by the piezoelectric method were Fourier analysed. The amplitude spectra were discussed from the point of the predominant frequency of the stress waves. The relation between the predominant frequency and the weight of the explosive charge is defined, that frequency is indirectly proportional to the fifth root of the weight of the charge. By comparing that experimentally obtained relation with the formula of the source frequency, given by F. G. Blake, the expression for calculating the predominant frequency of the stress waves generated by the explosive sources was determined.
