ABSTRACT:
A distinction of the method is that, at the moment of release of ore, the ore flow in the zone of an outlet opening is divided into at least two parts by a vertical plane, and the ore flow is caused to swing transversely with respect to the direction of ore flow by alternately changing the density of ore in the portions of the flow. Oversized lumps of ore delivered to a loading drift are transferred along a ramp by-passing haulage vehicles to ventilating and man roads which are arranged at the level of haulage crosscuts and connected thereto at points opposite to the loading drifts. An apparatus for carrying out the method includes a working surface of a platform having three rigidly interconnected portions, the end portions extending parallel and at different levels, and a central portion inclined in the direction of ore flow.
