In the extractive industry of carbonated ornamental rocks, the presence of discontinuities, size of grain, colour, textural anisotropy and porosity are factors that determine the extraction planning and their economic viability. This characterization is important for the planning and scaling of the exploitation. The objective of this work was in first, using the penetration radar in the soil (GPR), to identify and determine the spatial distribution of these elements. The choice of this non-destructive geophysical method to perform the work was because it is a fast method of inspection, having a good horizontal and vertical resolution, and relative precision. for this purpose, a PULSEEKKO GPR (SENSORS & SOFTWARE) acquisition equipment was used, with a system of two bi-static antennas (transmitter and receiver), unshielded, with a frequency of 100 MHz, using the reflection method with a common offset and with an antenna separation of 1,00 meter (m), at the pre-defined locations at each level of the quarry. The acquired data were subsequently processed in the REFLEXW® vers. Software. 7.5.9, from SANDMEIER-GEO®. The multiple profiles obtained (radargrams) [1], [2], which were compared with the corresponding exploitation fronts. This comparison allows validating the methodology used in the identification of existing structures, their vertical and horizontal limits and spatial relations between them.
