ABSTRACT:
An improved hydraulic mining tool apparatus for the recovery of minerals from subterranean formations is disclosed wherein the drill string, which extends from ground surface into the mineral deposit, is adapted to be maintained stationary during the mining operation while the mining tool, mounted to the lower end of the drill string, is adapted to rotate within the mineral formation. By maintaining the drill string stationary within the formation, frictional drag forces and tortional forces exerted on the apparatus are minimized thereby substantially reducing the input power requirements and reducing the possibility of a twist-off of the mining tool within the formation. The present invention additionally discloses a multiple stage slurry transport system for increasing the recovery rate of mined minerals from deep subterranean formations and further includes a tri-cone cutting bit attachment, mountable to the lowermost end of the mining tool which provides a rock crushing and force-feeding effect of mined materials into the mining tool.
