Study of geodynamic situation cut off parts of the plots using ergonometry with the open method of field development

Modern methods for calculating the safety factor of the sides of the open pit do not take into account the parameters of the modern geodynamic activity of the instrument array. The article presents the results of the first stage of research on the unique capabilities of radonometry to solve this problem. The studies were carried out in the instrument areas of the Shubarkol coal deposit. Terrigenous-carbonate sediments represented by fine and coarse-grained sandstones, siltstones, mudstones, loamy rocks and coals take part in the geological structure of the deposit. The stress-strain state of the rock massif in the area of the Shubarkulsky coal deposit is very heterogeneous. The nature of the deformation processes of the sides of the section is constant and moderate. Here, a discrete distribution of deformation sections is characteristic. The article presents the methods of radonometric measurements, the processing of measurement results and the results of studies of the near-surface sections of a coal mine, aimed at developing a methodology for quantitatively taking into account the degree of modern geodynamic activity in the design of open pit sides. Based on the results of radonometry, the geodynamic activity indices identified in the study of the deformation zones of the instrumentation areas are determined. An algorithm for further studies of the problem of taking into account the degree of modern geodynamic activity in determining the safety margin of open pit sides is determined.The accumulation and generalization of empirical information about the deformation processes of open pits and the results of studies of the geodynamic situation of dash sites, determined using radonometry, will make it possible to modernize the methodology for calculating the margin of safety margin of the sides.

Keywords: rock massif, modern geodynamic activity, radonometry, open pit, deformation zone.
