摘要： A mining machine includes a boom, a cutter head, a valve, and an actuator. The boom defines an internal chamber and includes a first end coupled to a frame, a second end, and an opening in fluid communication with the internal chamber. The cutter head includes a plurality of cutting bits and is supported on the second end of the boom. The valve is coupled to the boom and is movable between a closed position in which the opening is covered and an open position in which the opening is at least partially uncovered. The actuator is coupled to the valve to selectively move the valve between the closed position and the opened position.

摘要： Systems for installing roof support sheets on a mine roof. One system includes a support frame, a lifting system, and a feeding system. The support frame holds a plurality of roof support sheets. The lifting system lifts at least one of the sheets from the support frame. The feeding system obtains the at least one sheet from the lifting system and feeds the at least one sheet toward an installation apparatus for installation on the mine roof. The lifting system includes a shoe and at least one arm for moving the shoe to engage and move the at least one sheet. The feeding system includes a drive assembly and a support. The drive assembly engages and moves the at least one sheet toward the installation apparatus, and the support supports the at least one sheet moved by the drive assembly.
