FIELD: mining.SUBSTANCE: device comprises a base of an end head of a bottomhole conveyor with spherical hinged guides of an unloading table, a base of a drift conveyor with a coupling support, jacks of haulage and guiding, with a section of a tail drum, a ramp link. At the same time bases of the end head of the bottomhole conveyor and the drift belt conveyor are matched in the vertical plane and are equipped with cuts of the side (cross) overturning along the axis of the drift conveyor, besides, the length of the cut of the bottomhole conveyor is more than the width of the cut of the drift conveyor by the value of the permissible displacement of the bottomhole conveyor relative to the drift one, and is equal to the length of hinged guides, when the spherical support of the unloading table is installed on the axis of the rock mass overturning, spheres with guides are not installed on the drift conveyor.EFFECT: increased reliability of a device, lower error of measurements and provision of a single-process flow technology of coal stoping in longwall faces within a single cycle.12 cl, 9 dwg |
