Prediction of Geological Heterogeneities in Coal Seams Using Seismic Technique

The results of underground seismics application to predict geological heterogeneities in coal seams in order to increase the rates of coal production and to improve mine safety are presented. Developed original seismic procedures and processing of the acquired data enable to identify and trace zones of increased fracturing and faulting of coal-rock mass as well as changes in lithology of the bottom and top of coal seams.
