| Summary: | The relevance of the study is specified by the necessity not only to identify the surface distribution of cracks, but also the degree of vegetation of the rock when evaluating the fracture of the main rocks as applied to the facing stone deposits. In modern practice, when developing deposits, the rock with various types of distributed cracks can be detected. The further development of deposits of facing or building stone depends on the correct and rational solution to this problem. The solution to the problems of localization of the distributed propagation of cracks can be based on the attraction of modern technologies and introduction of engineering geophysicists into practice, allowing research based on the study of spatially oriented cracks in the rock mass. Analytical studies and experimental observations in natural conditions make it possible to preliminarily differentiate area of study by degree of demolition geological material mass, as well as to make a qualitative assessment of block raw materials. The main aim of the research is to selection of the optimal complex of geophysical methods for studing the propagation and localization of fractures in a rock mass. Methods: GPR studies using OKO-2 equipment with 150 MHz and 1200 MHz antennas. Results. Based on the study, the authors have proposed to use two types of antennas for penetrating to different depths. The general characteristic of the block stone deposit is obtained, the study area is allocated according to the degree of fracture. The presented methods reflect the effectiveness of the study of fracturing in a facing stone deposit using georadar. |
