these dynamic phenomena also occur there. Techniques have been developed to increase the stability of mine workings and eliminate the shooting of rocks. In addition to such a negative phenomenon as shooting, there is another problem of stress redistribution in the mountain range. Previously, the process of isotropy and anisotropy of the stress state of rocks was described [6]. This process significantly affects the degassing of the coal mass, without which it is virtually impossible to work in gas-saturated coal mines. An important link in the preparation of the coal mass for coal mining is its preliminary degassing. Anisotropic stresses sometimes become a significant obstacle during this stage of work. There is a clamping of the drilling tool in the rock mass, and the removal of the tool (drill pipes) often leads to its rupture. Taking into account the distribution of the stress state in the rock mass, the correct location of well drilling directions for advanced degassing of the massif, can significantly increase the load on coal mining machines and increase coal production, while maintaining a sufficient degree of mining safety. CONCLUSIONS Mining geology, as one of the areas in mining, is an important link in preparing an object for its subsequent development. The constant increase in the depth of work, for example, in the coal industry, requires constant monitoring of the stress-strain state of the rock mass and timely response to changes in the conditions of its occurrence. A set of techniques developed at the Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine over the past decades can be used in the development of various deposits, both in sedimentary and crystalline rocks. The authors of the publication established and described the formation of quasicrystals in rocks and substances of different systems; developed a method for identifying disturbed zones for predicting gas accumulations, thermal, gas-dynamic and dynamic phenomena; developed a method for identifying three substages of catagenesis, which differ in properties, the presence of free methane, the formation of gas-dynamic phenomena in them; developed a method for identifying schematic maps of paleoflows associated with elevated methane contents; developed methods for increasing the stability of mine workings to dynamic phenomena.
