Abstract
The process of shear of a rigid rough plate in a granular medium is considered. The influence of three factors is analyzed: stiffness of loading, weak shocks and air flow. It is shown that weak shock actions and air flow, either separately or jointly, can act as a trigger of uncontrolled dynamic release of elastic energy in rock mass.
