Abstract: The influence of the deposit geological structure on the risk of technogenic accidents in the mineral deposits development have been studied in the study. The technogenic accidents take place due to the growing stress-strain state of rock mass. The rock mass is a very complex environment in which deformation processes of different nature simultaneously occur with the mining operations. The monitoring of the slope deformation is very difficult task, due to the fact that the full-scale field studies are considered to be complicated, expensive and require intensive labor consumption and a long period of time. Therefore, modeling (modeling of equivalent materials, computer modeling) gives the possibility of studying such geomechanical processes that do not provide any analytical methods or observations and measurements in natural conditions. Such factors as geological and hydrogeological structure of the deposit, pit wall parameters-depth, the angle of pit wall will influence on the stress-strain state. Therefore, it is necessary to consider all of these factors to obtain a complete and accurate picture of the deformation slop in computational modeling.
