Besides the problem of adapting 2K - 52MU machine to la TR - 5 scraper conveyer, the study of stability of the machine on conveyer was required, in faces with individual supports. To this end stability coefficients of the machine were determined in cutting and loading coal on the conveyer, and even in blocking the drum at the face. The study was made for maximum 250 kN traction force and variation of the inclination of the face in the range of 0 and 300 for three cases of machine movement towards the face.
