【 摘 要 】

The object of study was the rescue complex for carrying out high-speed workings of small section, the main task of which is to evacuate miners caught in an accident. The aim of the work was to determine the parameters of the rescue complex, part of which is a mechanized walking support. Laboratory studies of walking support parameters were carried out to determine the actual value of the coefficient of resistance to movement (kres). It is established that the movement force of the section-jointed walking lining is based on the mass of its parts, size and physical and mechanical properties of the side rocks and roof, expressed in the steady state by an exponential dependence on the time and step of the advance. And the experimental value of the drag coefficient of the walking lining is in the interval of 3-5.
