ABSTRACT:
An improved hydraulic mining tool is disclosed wherein the major components of the tool are formed as separate discrete modules, each including a high torsional strength common mounting flange which permits the modules to be interchangeably attached to one another in varying axial orientations to yield a composite mining tool structure adapted to meet the particular mining requirements of the mineral formation. The mining tool discloses axial and radial slurry inlets, both of which include means for feeding quantities of mined minerals toward the slurry pump of the tool. The feeding means may be adjusted from ground surface during the mining operation to meter the amount of material entering into the slurry pump, thereby maximizing mining efficiency in varying consistency mineral formations.
