Abstract
This article summarizes the results of numerous experimental studies of the physicomechanical properties of rocks from deposits of Zakhidnyi Donbas. The analysis of the obtained data allowed us to reveal the zonal nature of their change. Regularity has been established for increasing the strength parameters of rocks in the direction from west to east, the mechanism of which is explained, among other things, by the influence of Coriolis forces arising from the daily rotation of the Earth. It has been established that for more durable rocks, such as sandstone, the change in strength characteristics in the roof and floor is insignificant, whereas for weaker mudstones and siltstones, there is a significant difference in the above strength parameters. A generalization of the test results of Zakhidnyi Donbas rocks showed a large variation in their properties under the conditions of the achieved depth of the reservoir under development, which is due to the variability of the composition, structure, texture of the rocks and the degree of epigenetic transformations.
Highlights
One of the important factors determining the parameters of mineral development systems, the nature of the various production processes in mining and processing, as well as during mining for various purposes, is the availability of a certain set of data on the physical and mechanical properties of the massif

Summary
One of the important factors determining the parameters of mineral development systems, the nature of the various production processes in mining and processing, as well as during mining for various purposes, is the availability of a certain set of data on the physical and mechanical properties of the massif. Knowledge of the rocks properties is necessary in the extraction of minerals, and in the construction of various buildings, the erection of hydraulic structures, tunnels, road construction, etc [1, 2] In this connection, the study of the physicomechanical properties of rocks, which are an important component in calculating the stability of underground structures, roof supports and guard structures of mine workings, acquires great importance. The study of the physicomechanical properties of rocks, which are an important component in calculating the stability of underground structures, roof supports and guard structures of mine workings, acquires great importance Many scientists, both in our country and abroad, paid great attention to the problem of assessing the stability of the rock massif in their works [3 – 5].
