Abstract:

The paper discusses the task of pressing a rock-breaking mining machine on a rock. Based on the physical content of the study, it is considered that the rock is a layered prismatic body, and the working body of the weapon that is in contact with it is absolutely rigid. Accordingly, the stress-deformed state of a prismatic three-layer body is studied when the load is transferred to its surface by means of a rigid body, and there is a rigid or creeping contact between the layers.

Keywords: Machine, rock, pressure.
