Application of radiation seismography to determine the contours of ejection-hazardous geological disturbances in the pillars of the Starobinskoye field prepared for mining

Abstract

Radiation seismic tomography is used in seismic exploration as one of the data interpretation techniques. It can be used to reconstruct a detailed picture of the rock structure in the space between two mine workings. The spatial distribution of attenuation or velocity of elastic waves is calculated using linear integrals or their approximations along the rays and reproduced digitally. The solution of large systems of linear equations linking the measured integral parameters and characteristics of the studied geological objects is performed using various algebraic algorithms. The analysis of elastic wave propagation between excavations is based on the concepts of geometrical optics. The possibilities of the reconstruction algorithms are illustrated in the process of processing experimental results of mine studies. The method allows to reproduce two-dimensional distribution of variations of the studied parameters.
