FIELD: mining.
SUBSTANCE: invention relates to mining and can be used for the destruction of rocks. Mechanical block is made in the form of a spacer, including a spacer with a central hole and a stop structure, it is equipped with a rod element passing through a hole in the spacer means with an outlet beyond it in the direction of the production mouth. At the end of the rod element, a profile structure is made, which is a means of gripping it in the process of preliminary wedging. Thrust structure is spatially disposed in opposition to the spacer means with the formation of a gap between their mutually converging end faces. Spacer is either an elastic umbrella structure or a rigid pressure structure. Between the mutually converging end faces of the spacer and the stop structure, an additional locking device is provided, equipped with a central hole and in contact with said surfaces of the stop structure and the spacer. Rod member is kinematically connected to the spacer by means of a ratchet engagement of the umbrella type, locking elements of which are located along the length of the rod element and on the inner surface of the opening of the spacer with the possibility of their pre-fixing before installing the breaker into the cavity of development. Additional fixing means may be in the form of an elastic element made of rubber or in the form of an ampoule which is filled with a solidifying structure.
EFFECT: invention makes it possible to increase the reliability of locking the die in the development.
