A complex model of the formation of an external disturbance vector on the axial crown of the executive body has been developed, taking into account the influence of mining and geological conditions and operating parameters of the combine on the process of destruction of the mountain range, which consists of models of the destroyed array and the face surface, finding the coordinates of the tip of the cutter in the face, evaluating the conditions of contact of the cutter with the array, determining the parameters of the process of destruction of the array by cutters crowns for determining the cutting and feeding forces on the cutter, taking into account the fulfillment of the contact condition of the cutter with the face. The adequacy of the mathematical model was assessed by comparing the indicators obtained during model and experimental studies: average fracture power per cycle, theoretical productivity, specific energy consumption per cycle, and the duration of face treatment.
