Problem of determining magnitude of rock pressure on roof supports in underground workings
Angle of internal friction of rocks has to be taken into account; maximum pressure on beams will be established in course of evolution of rock deformation and decrease in time of rock strength; maximum rock pressure will remain constant in time under constant parameters of pressure relieving arch.
