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.

Air flow system for mining machine

A surface mining system for removing material from a mining face generally includes a conveyor extending substantially parallel to the mining face, a miner supported by and moveable along the conveyor, and a conveyor translation device associated with the conveyor and operable to move the conveyor and the miner toward the mining face. A method for advancing a surface mining longwall system generally includes moving the longwall shearer along a face conveyor, operating load translation devices to move the face conveyor and the longwall shearer toward the mining face, resetting a first group of load translation devices, and then resetting a second group of load translation devices. A load translation device generally includes an actuator, a ground drilling device coupled to and moveable with a portion of the actuator, and a frame coupled to and moveable with another portion of the actuator.

Advancing longwall system for surface mining

A side shifting conveyor is provided for a surface mining operation. The conveyor generally includes conveyor sections and conveyor translation devices. Each conveyor translation device includes a drive operable to move the associated at least one conveyor section in a direction substantially perpendicular to the conveying direction. The conveyor further includes a controller operatively coupled to each drive for controlling operation of the drive and coordinating movement of the conveyor sections. A method for moving a conveyor in a surface mine generally includes sensing that a surface miner operable to deposit material onto the conveyor sections has moved beyond one of the conveyor sections, fixing a position relative to the surface mine of a conveyor translation device associated with one of the conveyor sections, and operating the conveyor translation device to move one of the conveyor sections in a direction substantially perpendicular to the conveying direction.

Conveyor system for continuous surface mining

A surface mining system removes material from a surface mining block that has a substantially vertical and laterally extending mining face. The surface mining system generally includes a miner moveable in a lateral direction along the mining face, a face conveyor extending along the mining face, and conveyor translation devices associated with the face conveyor and operable to move the face conveyor toward the mining face as material is removed. The miner includes a rotating cutting member mounted to an end of a vertically ranging cutting arm and operable to remove material from the mining block. The face conveyor includes a discharge portion and is operable to convey material removed from the mining block toward the discharge portion. Each conveyor translation device includes a secured configuration substantially fixed with respect to the mining face and an unsecured configuration moveable with respect to the mining face.

Continuous surface mining system

The present invention provides a mining apparatus for installing bolts into a mine entry, said apparatus including: a frame having a forward end, a rearward end and lateral sides; an upstanding bolter support wall attached to said forward end of said frame; a laterally extending guide frame mounted to said support wall which extends along a lateral plane which is generally parallel to the support wall; at least one bolting rig slidably mounted to said guide frame; and translation means for selectively moving the bolting rig laterally along the guide frame relative to the support wall.

Extendible drill support frame for mining apparatus and roof bolting equipment

The invention provides an apparatus ( ) for installing bolts into a mine entry, said apparatus including: a frame ( ) having a forward end ( ), a rearward end and lateral sides; at least one bolting rig ( ) operatively mounted to said forward end of said frame; at least one roof support member attached to said forward end of said frame ( ) separate from said bolting rig ( ) for selectively supporting said mine entry as bolts are installed therein; and an operator station ( ) on said frame for supporting an operator thereon during operation of said at least one roof support member.

Roof support arrangement for mining apparatus and roof bolting equipment

The invention provides a vehicle which employs hollow structural members to store and cool hydraulic fluid used by the vehicle or by equipment located thereon. The preferred form of the invention provides an apparatus for installing bolts into a mine entry said apparatus including: a frame having a forward end, a rearward end and lateral sides, said frame defining a generally horizontal work area; at least one drive for propelling said frame within said entry; at least one bolting rig attached to said frame; a deck member attached to said frame and covering said frame for supporting an operator thereon; and a return oil tank incorporated into said frame to receive return hydraulic oil from said bolting rig or rigs.

Oil tank arrangement for mining apparatus and roof bolting equipment

The present invention provides a storage pod for storing equipment and parts for use in underground mining operations, said storage pod being self supporting and removable from a transport or operational vehicle whereupon said pod is carried in use, said pod comprising a generally rectilinear body which forms an open topped upper compartment having a front wall, a rear wall, side walls and a floor, and a lower compartment located below said floor, said lower compartment being divided into a series of elongated storage slots, said slots being accessible from the front and/or rear of the pod. The invention also provides an underground mining machine in assembly with a pod of the type described above, the vehicle and pod having cooperating locking formations thereon for releasably locking the pod the vehicle for the duration of a mining operation and adapted to allow removal of the pod from the vehicle and replacement thereof with another pod as and when required in use.
