Abstract: Investigation of the internal structure of the rock massif (layer-step, schis-tosity) and the parameters of its fracturing (azimuths and angles of inci-dence of fracture systems) is of great importance in calculating the param-eters of drilling and blasting operations. Conventional exploration methods (drilling of exploratory wells) are quite expensive, and their use in large volumes is not always justified economically. At the same time, too large a grid of exploratory wells often does not give an accurate picture of the structure of the massif in each specific place of drilling and blasting opera-tions. To clarify the structural parameters of the local rock massif (within the blast-blasting block), it is expedient to use the georadiolocation method. A low-cost and operational georadar survey of the drilling and blasting unit gives a complete picture of the fracture and layer anisotropy of the massif (or its absence), the presence of watered areas. The data of such a survey can be used to adjust the parameters of drilling and blasting operations in order to optimize the balance between the consumption of explosives and the given quality of crushing rock mass.
