Abstract

This paper presents the results of a comprehensive survey of a coal-bearing rock mass conducted by means of a combination of geophysical methods. The task of a comprehensive survey is to establish the relationships between the manifestations of mining and geological processes in the preparatory workings and the parameters of electromagnetic emission and high-frequency radio wave scanning. The estimation of the parameters of unsteady geophysical fields, resulting in the stress-strain state of the rock mass, was carried out using the ANGEL-M complex. The assessment of decompression and the presence of fracturing of rocks around the belt road was performed by the OKO-2 GPR system. Analysis of the results of the examination of underground mine workings using the “ANGEL-M” and “OKO-2” complexes shows a high degree of convergence of the state of the workings and instrument readings. Cave-in places of in the workings are located in high amplitude regions of radio waves. Identification of the development sites prone to geodynamic manifestations will allow to take measures for strengthening the frame support in advance, preventing deformation of the extensible belt conveyor. The implementation of a comprehensive survey will improve the reliability of transport conveyor lines and the safety of mining operations.
