Abstract: Application of numerical modeling of fast processes when solving the field-scale tasks remains an actual scientific and research problem. It is impossible to make observations of the effect on the rock mass located beneath the previously mined open-pit reserves. Two ways of studying are possible, i.e. physical and computer (numerical) modeling. Application of physical modeling requires availability of laboratory facilities and is concerned with significant financial costs thus being less preferable for studying the impact of processes that take place during blasting operations on the rock mass located at depth, but where underground mining operations are not yet underway and there is no possibility of direct measurement of the seismic signal from the blasting operations. Surface drilling with the installation of depth sensors also requires significant financial costs and its application is not always possible to foresee, as the activities may be separated in time by decades and underground mining was not previously planned. The cost of research with the use of numerical modeling is much cheaper and in addition to high qualification of the expert requires only the availability of software and a high-performance computer for the calculations. This paper provides an example of numerical modeling using the CAE Fidesys software suite to determine the effects of technological factors in open pit mining on the mining conditions of the Polysaevskiy seam reserves in conditions of the mine named after A.D. Ruban. A complex approach was used to create the model: from optimization of the blast hole geometry up to step-by-step calculation and analysis of the obtained results. A complex approach was used to create the model: from optimization of the blast hole geometry up to step-by-step calculation and analysis of the obtained results. This approach made it possible to obtain a qualitative and quantitative representation of the rock mass deformation distribution in the area of the Polysaevsky-2 seam as the result of previous surface drilling and blasting operations.
