Mathematical modeling, analytical studies, analysis of research parameters, laboratory studies. Results. The article substantiates the method for determining the angles of inclination of the fracture site under a volume uneven-component loading. To determine the destructive stresses acting on the fracture site, the formulas have been obtained for determining the angles of rotation of the fracture site under volumetric uneven-component loading. The parameters of the stress state and their values at the moment of destruction of the coal samples have been established. A comparative analysis of the obtained theoretical results with the results of a laboratory experiment has been carried out, where the angles of inclination of the fracture plane in the coal samples have been determined geometrically. At the same time, the average value of the error is 2.6%. Scientific novelty. The dependences for determining the angles of inclination of the fracture site in the case of volume unequal-component loading from the stress state have been presented for the first time. Practical significance consists in determining the parameters of the formation of man-made cracks in the process of destruction of rocks or coal in a volumetric unequal-component load. Due to the angles of inclination of the destruction site, it is possible to determine the value of the parameters of the destructive stresses. According to the parameters of the position of the crack systems of geological disturbances in the rock massif, it is possible to determine the values of the principal stresses.
