The soil oscillations were investigated in the conditions of an active mine. The specified oscillations are due to impulse excitation and oscillations that registered during continuous seismoacoustic monitoring, when the main source of oscillations is the tunneling machine. The results of the observations formed the basis of the constructed mathematical models of the propagation of oscillations in a complex environment and their transformation into geophone signals of various types. The recorded noise-like signals determined the requirements for determining the spectral estimates. Processing methods were tested on model signals obtained by passing "white noise" through a specially designed filter. The developed methodological approach is based on continuous monitoring and evaluation of transformations of seismoacoustic signals, from the sources to the formation of criteria, as transformations of random functions The proposed prognostic parameters and criteria are calculated based on the power spectral density characteristics of the registered signals. The proposed parameters are resistant to variations in the spectrum construction parameters and sample variability, in contrast to the normatively established.   Product Description popup.authors Babets Dmytro V.
