ABSTRACT:
An improved hydraulic mining tool apparatus for recovering minerals such as tar sands and the like from subterranean formations is disclosed, wherein plural cutting jet nozzles, adapted to hydraulically dislodge mineral particles from the formation are positioned to generate a hydraulic couple rotational force upon the mining tool and thereby reduce overall power requirements for the apparatus. The plural cutting jet nozzles are connected to one or more flow conduits extending axially within the mining tool apparatus or alternatively may extend from a common sealed reservoir formed within the annulus of the mining tool. The present invention additionally discloses the use of a tri-cone cutting bit assembly positioned upon the lowermost end of the apparatus which may be activated and de-activated from ground surface to selectively provide a rock crushing and force-feeding of mined material during operation as well as during the lowering of the mining tool into the mineral formation. The mining tool apparatus further incorporates one or more tool casing extensions, selectively mountable between the tri-cone cutting bit assembly and the slurry inlets of the tool to insure that the slurry inlets remain clear from rock obstructions accumulating about the lowermost portion and tri-cone bit assembly of the tool during the mining operation.
