The article considers the factors that directly influence the operation of the lip seals to seal the gap between the piston and the working cylinder in hydraulic props of mechanized supports, this directly affects the tightness of the props and, as a consequence, the safety of work in the production face. A description is given of these factors, which is supported by practical calculations obtained from the results of finite element modeling of lip seals of various designs at different pressures of the working fluid and sealed gaps. The problems of sealing rough surfaces with rubber-like materials are considered. The classification of these factors according to the degree of generalization and the functional interaction between each other is proposed.
