METHOD FOR LOWERING THE FLOORS OF GALLERIES, ETC., IN UNDERGROUND MINES, ETC.

摘要

The equipment proposed includes a floor-loosening machine (1) with running gear (4) and with a loading shovel (6) which may be fitted with hammer drills, a crusher (2) comprising at least one crushing unit (8) mounted on running gear (11), and intermediate conveyor means (3) connected after the crusher (2). In order to be able to use a normal loader with this equipment, the crusher (2) is located in front of the floor-loosening machine (1) in the unlowered part of the gallery, thus enabling the material extracted to be transferred directly from the loading shovel (6) to the crusher (2).
