Abstract
In the article, the authors conducted a study of the mechanics of the underlying coal bed. At the same time, the movements of the array are determined taking into account the reactions of the mechanized support with excavation functions. The total load on the supporting elements for single-support and multi-support supports is determined. The definition of the working resistance of the hydraulic support struts is also given and its calculation is given. In order to comply with the working condition that the support must be controlled in the plane of the formation and in the plane perpendicular to its occurrence, and to ensure the directional movement of its section following the movement of the face, it is necessary to take into account that the height and extensibility of the support struts must correspond to the power of the formation and be taken depending on the actual values of power fluctuations within the excavation column
