Abstract

The problem of determination of parameters of the elastic waves source in the fractured rocks is complicated by the presence of a variety of free surfaces. We study the influence of a structural element of jointed rock formation with specific site D close to the length a of the radiated pulse (a~D) on the initial field. In this work the problem turns into finding the spectrum of the natural vibrations of the solid of finite dimensions, and on extracting this one from the general spectrum of the recorded acoustic signal. It seems to be important for improving the spectral method for detecting the inhomogeneities with share boundaries and determining their dimensions.
