    摘要: A tool assembly (4) for working a material (R) such as breaking rock. Assembly (4) includes a tool mounting (17) having a fixed section (18), and a movable section (19) for movement relative to the fixed section (18) in a working direction (D.sub.W) and an opposite return direction (D.sub.R). A tool (34) is mounted on the movable section (19) for movement relative thereto in the working direction (D.sub.W) and return direction (D.sub.R). Limit means (49,50) on tool (34) limits relative movement between tool (34) and movable section (19) to between a tool operative position and a tool operated position. During a working stroke, tool (34) is engaged with material (R) and moved in working direction (D.sub.W) from the operative position to the operated position and thereafter in unison with the movable section (19) under action of a working force applied to tool (34) thereby to work material (R). The tool assembly (4) also includes biasing means ( 29) acting between the fixed section (18) and movable section (19) to absorb the applied tool working forces transferred from tool (34) to the movable section (19), and also to provide a restoring force to the movable section (19) for returning the movable section (19) in return direction (D.sub.R) upon conclusion of the working stroke of the tool (34).

    摘要: A first mobile mining machine for cutting mining tunnels in hard rock, which includes a horizontally swinging wheel-like cutterhead assembly mounted on a crawler and base frame assembly. The cutterhead assembly consists of a transverse horizontal axis wheel-like drum on which are multiple peripherally mounted rolling cutter units.A second mobile mining machine for cutting mining tunnels in hard rock, which includes a horizontally swinging and vertically ranging wheel-like cutterhead assembly mounted on a crawler and base frame assembly. The cutterhead assembly consists of a transverse horizontal axis wheel-like drum on which are multiple peripherally mounted rolling cutter units.A method of cutting mining tunnels in hard rock which includes the steps of providing a wheel-like cutterhead assembly for cutting the hard rock, rotating the cutterhead assembly about its horizontal axis, plunging the rotating cutterhead forward into the hard rock, sweeping the rotating cutterhead assembly sideward in a first horizontal direction through the hard rock, plunging the rotating cutterhead forward into the hard rock, then sweeping the rotating cutterhead sideward in the other horizontal direction, and then repeating the last four steps.
