FIELD: mining.
SUBSTANCE: present invention relates to the field of mining machines and, in particular, to a conveyor chute for a long face mining system. A conveyor chute is proposed for maintaining a section of a dredging conveyor, passing along the face and located between the face and developed space. The conveyor chute includes a support plate, a toe, and a heel. The support plate includes the first side made with the possibility of location near the face, and the second side made with the possibility of location near the developed space. The toe is located adjacently to the first side of the support plate, and it includes a contact surface of the toe, forming a surface area of the toe. The heel is located adjacently to the second side of the support plate, and it includes an eyelet and a contact surface of the heel. The eyelet is made with the possibility of connection to a forward movement mechanism. The contact surface of the heel forms a surface area that is more than the surface area of the toe. A dredging conveyor is proposed, containing a set of interconnected conveyor chutes.
EFFECT: decrease in the moment acting on a chute, minimization of lifting or upward deflection of a toe.
