Abstract: During the attachment of a highwall mining in the process of a lining section thrust the collapse of a culm contact layer and the roughness of the soil as well as the local introduction of foundations takes place. The current state standard of Russia, establishing the basic parameters and general technical requirements for mechanical linings only the average pressure on a layer soil is regulated. However as practice shows the focus on medium pressures does not correspond to the real operation conditions for mechanical linings and the standard needs a serious adjustment in this respect. The method is offered which provides the calculation of contact pressures on a layer soil, provided by a foundation beam along the length of a lining single-row shield section, taking into account not only the efforts of hydraulic props but also the efforts in rear fence levers.
