The basic part of any mining machine is the operating body used for mine working. The parameters of the mining machine are particularly affected by the geometric and force parameters of their operating bodies. The knife shape is one of the geometric indicators of the mining machine cutting part. The existing methodology for calculating a geokhod cutting body does not take this indicator into account. The purpose of the work is to determine the influence of operating body knife shape on the strength of the blocked cutting. The research shows that the knife shape affects only the forces for overcoming the frontal resistance of the soil by the front edge of the knife. It is possible to determine the influence of the cutting edge shape of the operating body on the force of blocked cutting. As a result of the study, it was revealed that when the knife is deepened to the entire cutting depth and when it destroys the face corresponding to its shape, the knife shape does not influence the strength of the blocked cutting.
