. The study of the rock stability properties and parameters is an integral part of ensuring safe subsurface use in the process of human impact on the rock mass. In order to understand the spatial variability of serpentinite rocks properties and parameters, research has been carried out, including laboratory tests with subsequent determination and analysis of laws governing the changes in their physical and mechanical properties. Research methodology. In this study, physical and mechanical properties of rocks of the Zhitikarinsky (Dzhetygarisnky) quarry were determined and analysed. The research methods included laboratory uniaxial compression-tensile tests, direct measurements of dry unit weigh, and the statistical analysis of the data obtained. Research result. According to the results of tests and statistical data processing, the values of physical and mechanical properties were obtained for ten rock types collected at the marginal area of the Zhitikarinsky quarry. The graphs show an analysis of laws governing the changes. With an increase in the degree of serpentinization, the values of strength characteristics decrease significantly. Correlations of physical and mechanical properties of serpentinite rocks of the Zhitikarinsky deposit are established.
