Abstract: A double-headed rock cutter comprises two cutting heads mounted on either side of a stem, wherein each of the cutting heads has its own output shaft to drive it in rotation. The stem houses a single input shaft that, in use, receives power and is engaged with both the output shafts to drive both cutting heads. Wherein, the engagement between the input shaft and the two output shafts is such that the output shafts are able to be set relative to each other at a user determined radial angle about the axis of the input shaft. This allows the user control over the distance between the two resulting parallel swathes that are cut by the respective cutting heads.

Abstract: A machine for improved excavation of underwater rock that eliminates failures due to over-stressed cutting teeth 3 by positioning each hardened tooth for optimized Kinetic Energy. It has a plurality of blades 7 each connected between a back ring 6 and a forward rim 5, with a plurality of spokes 4 connecting rim 5 to a hub 1. Teeth 3 are mounted on the leading edge of each blade 7 approximately equidistant from the cutter axis of rotation 2, allowing each tooth 3 to have the proper combination of velocity and cutting force required to shatter massive, hard rock. As a result, all teeth 3 in the present invention have approximately the same peripheral velocity; have adequate Kinetic Energy to shatter rock upon impact, and are subject to approximately the same maximum stress during rock excavation.

Abstract: A drum-type miner having a plurality of water jet nozzles which cut independently of the mechanical bits is disclosed. The drum-type miner may be configured in either a hard-head or a ripper-chain design. The unique combination of mechanical and hydraulic cutting results in higher rates of penetration and improved productivity. Moreover, because the mining face is pre-scored by the water jets, the amount of wear on both the mechanical bits and the motors may be significantly reduced.
