Abstract

The paper presents the results of the instrumental observations processing, allowing to obtain information about the structure and interaction of thepartings of heterogeneous fault-block geological environment. We have proposed a comprehensive method of active vibro-seismic monitoring that uses two types of signal: a signal with a linear frequency modulation (LFM) and a harmonic signal.

Previously, the authors presented the data of experiments on the excitation and recording of signals with linear frequency modulation, allowing to determine the absolute velocity of the longitudinal wave in a block geological environment.This paper is devoted to the description and analysis of the experimental data processing results using a harmonic signal generated by a mobile vibration source.The usage of a harmonic signal makes it possible to determine the transient response of the medium, the phase component of which in turn allows us to track the changes in velocity of the longitudinal wave from experiment to experiment.

In accordance with the general tasks of identifying the areas of conjugation of lithospheric structures, we analyzed the results of experiments using the complex method of vibro-seismic monitoring. The results of the data interpretation on geological and geophysical materialsobtained using a heavy mobile vibro-seismic source give an idea of the local geological lithosphere structures, the localization of areas of dilatancy and the changes occurring in them.

Keywords:

block element method, dilatant type structure identification, block lithospheric structures, complex vibromonitoring method, harmonic signal
