- Аннотация: The use of deep GPR in the study of coal deposits from the surface is necessary to obtain a geoelectric section of tens of meters deep in media with strong dispersion and low resistivity. The advantages of GPR data in comparison with traditional methods of borehole geophysics are relatively low cost and the possibility of continuous surveying along with the profile or survey area, which allows, for example, to explore the territory of the field with a grid with a step of 1 or 2 meters to a depth of over 50 meters and a depth resolution from 10 centimeters. Using deep GPR in anthracite and coking coal deposits, we have determined the subsurface structures from the surface to a depth of 70 meters with great detail. Here, we show GPR transects, which allow bringing out bedding geometry, for example, a radio image of an anticlinal fold, formation sizes and angles of inclination, as well as relative electrophysical differences of coal seams.
