ABSTRACT:
This invention concerns a ripping platform for use in a mine to support the roof above an excavated stratum of mineral to facilitate excavation or ripping away of the roof to provide a roadway. In accordance with the invention a ripping platform to receive and distribute debris from a mine roof comprises a trough for location under the mine roof, a first deck within the trough reciprocable in a direction lengthwise of the trough at a level above the bottom of the trough, reciprocating mechanism for the deck located in the trough under the deck, an impeller member secured to one end of the first deck and extending downwardly from the deck to the bottom of the trough, and a second deck in the trough closely engaging the first deck, the first and second decks and the impeller defining a zone between the decks and the trough bottom that is substantially isolated from the debris, the said zone containing the reciprocating mechanism. Reciprocation of the first deck and impeller by the reciprocating mechanism will discharge debris from one end of the trough into a position at the side of the roadway.
