An analysis of previously performed studies has shown that the coefficient of stability of the working sides of quarries and coal mines is considered constant along the open surface of the side or along its height. The method of limiting equilibrium for the entire sliding surface allows us to obtain an average value of the coefficient. The stress-strain state of the instrument array of the working side of a coal mine under the action of a distributed load from an external rock dump is investigated. The use of the finite element method and modern geomechanics software packages made it possible to obtain indicators of the stressstrain state and stability of the board at any point of the instrument array. The regularity of the change in the coefficient of the stability margin of the side according to its height is established. The lowest numerical value of the coefficient is characterized by the lower ledges of the side, the deformation of which leads to the weakening of the upper ledges and the possible manifestation of landslides.
