摘要： A longwall shearer is positioned adjacent a face conveyor for transporting material that is cut from a mining face. The longwall shearer includes a chassis, an arm pivotably coupled to the chassis, a cutting drum for engaging the mining face, and a lump breaker for engaging material on the face conveyor. The chassis includes a first end and a second end, and the chassis is movable in at least a first direction that is generally parallel to the mining face. The cutting drum is rotatably supported on the arm. The lump breaker is pivotably coupled to the chassis about an axis, and the lump breaker includes at least one tooth for breaking apart the cut material.

摘要： The mining machine has a pair of rotatable drum members positioned in spaced parallel relation to each other and supported from the mining machine body portion by a pair of forwardly extending support arms. The support arms are pivotally connected to the mining machine and are arranged to move the rotatable drums in a vertical plane. The rotatable drums have a plurality of cutter bits extending radially therefrom to dislodge a pair of parallel kerfs of coal from the face that are slightly wider than the rotatable drum members. The kerfs cut by the rotatable drums extend beyond the side walls of the mining machine. Endless cutter chains with cutting elements thereon are reeved about the drums and the support arms. The endless cutter chains are arranged to dislodge a vertical kerf of coal as the support arms pivot relative to the body portion. A transverse cutter bar is supported within the periphery of the rotatable drum members. The cutter bar has a diameter substantially smaller than the diameter of the rotatable drum members and has radial extending cutter bits thereon along the length thereof to cut a transverse kerf in the coal. Means are provided to rotate the cutter bar relative to the drums to thereby form the transverse kerf between the spaced drum members. Other means are provided to revolve the rotatable cutter bar around the axes of the rotatable drums, so that the cutter bar can be moved to positions tangent to the lower, upper and intermediate portions of the rotatable drum members. The method of continuous mining includes sumping the rotatable cutter drums and transverse cutter bar into the coal and forming a horizontal transverse bottom kerf with the cutter bar and simultaneously forming a pair of vertical side kerfs with the drum member. The horizontal transverse bottom kerf is tangent to the lower edge of the vertical side kerfs. The cutter bar revolves about the axes of the rotatable cutter drum members to a location tangent with the front edge portion of the rotatable cutter drums. The rotatable cutter drums with the transverse cutter bar are is pivoted vertically relative to the mining machine body portion to form a pair of vertical side kerfs. The cutter bar forms a transverse vertical kerf between the vertical side kerf formed by the rotatable drum members. The endless chains form vertical side kerfs as the rotatable drums are pivoted upwardly relative to the mining machine body portion to form continuous vertical side kerfs. The transverse cutter bar is revolved about the axes of the rotatable drum members to a location adjacent the upper portion of the rotatable drum members and the rotatable drum members with the transverse cutter bar intact thereto is sumped rearwardly, completing the vertical side kerfs and a transverse upper horizontal kerf. With this arrangement, a block of coal is dislodged from the face.

摘要： A roller crusher is carried by a coal cutting mining machine which is, in turn, carried by a gantry for movement along the frame of a longwall face conveyor. The roller crusher is attached to the coal cutting machine by a U-shaped frame having hinge pins for pivotal movement thereof about a horizontal axis at the end of the machine which faces toward the oncoming stream of coal on the conveyor. The U-shaped frame supports a drive motor that is, in turn, coupled by a gear drive to the roller crusher. A piston and cylinder assembly is controlled to adjustably position the U-shaped frame and thereby the roller. The mining machine has support arms that are pivotal about horizontal axes and carry coal cutting drums to project into the working face of the mine.
