ARRANGEMENT FOR EXTRACTING EXTRACTION PRODUCTS IN UNDERGROUND EXTRACTION OPERATIONS IN CAVING

摘要

In the case of the arrangement according to the invention for extracting
extraction products in caving, the extraction product being removed downwards,
by way of a removal hopper (10), into a removal section (11) and being
transferred, from the latter, to a removal conveyor arranged in a conveying
section, wherein the removal section extends transversely between the
conveying section (13) and an auxiliary section (12) moved up parallel to the
latter, a loading ramp (16) is arranged in the removal section (11) and forms
a ramp surface which is oriented essentially transversely to the conveying
direction of the removal conveyor and is inclined in the direction of this
removal conveyor. In order for it to be possible to regulate the quantity of
extraction material removed by way of the removal hopper and to clear out the
removal section quickly and particularly straightforwardly when it has become
clogged with extraction material, the invention makes provision for the
removal section to be provided with a rail guide (19) which is fixed on the
floor or footwall (15), which extends in the region between the auxiliary
section and the conveying section, up to which the loading ramp (16) leads and
along which this can be displaced, by means of a displacement drive (20), in
the direction of the conveying section and in the opposite direction.
