    摘要: Controlling an output of a mining system. The control includes receiving, at a processor, a first signal associated with a position of the shearer, determining, using the processor, the position of the shearer based on the first signal, receiving, at the processor, a second signal associated with a load of a conveyor, and determining, using the processor, the load of the conveyor based on the second signal. The method further includes determining, using the processor, an output of the mining system based on the position of the shearer and the load of the conveyor and controlling a speed of the shearer based on the output of the mining system.

    摘要: A fluid delivery system for a longwall shearer. The fluid delivery system includes a flow control device and an electronic processor. The flow control device is in fluid communication with a nozzle positioned on the shearer, and in fluid communication with a fluid source. The electronic processor is coupled to the flow control device. The electronic processor is configured to receive a measure of a capacity parameter, and determine a model fluid flow based on the measure of the capacity parameter. The capacity parameter corresponds to a position of the shearer along the mineral face. The electronic processor is further configured to set an operational parameter of the flow control device based on the model fluid flow, and operate the flow control device at the set operational parameter.

    摘要: A tensioning mechanism for a conveyor system includes a support structure, a first carriage, a second carriage, and a brake mechanism. The first carriage is positioned proximate a first end of the support structure and is supported for movement relative to the support structure. The first carriage includes first rolls for receiving the belt such that movement of the first carriage modifies a tension in the belt. The second carriage is supported for movement relative to the support structure and includes second rolls and at least one return pulley. The second rolls are configured to support a portion of the belt extending between the first carriage and the second carriage. The brake mechanism is positioned proximate a second end of the support structure and includes a brake pulley and a brake selectively retarding rotation of the brake pulley. The brake pulley supports a portion of the belt extending between the brake mechanism and the return pulley.

    摘要: A cutting bit assembly includes a block, a bit sleeve, and a seal. The block includes a first bore and a fluid passage. The fluid passage includes a first portion and a second portion in fluid communication with the first portion. The first portion is oriented obliquely with respect to the first bore, and the second portion extends at least partially around the perimeter of the first bore. The bit sleeve includes a shank, a flange, and a second bore extending through the shank and the flange. The shank is positioned within the first bore of the block such that a surface of the flange engages a first end surface of the block. The seal is positioned between the second portion of the fluid passage and the shank to prevent contact between a fluid in the fluid passage and the outer surface of the shank.

    摘要: A fluid spray for an underground roof support includes a first housing portion, a spray outlet, a second housing portion formed integrally with the first housing portion, and a service port. The first housing portion includes an elongated shaft having a first end, a second end, and a first fluid passage extending between the first end and the second end. The spray outlet is positioned adjacent the second end of the shaft. The second housing portion is positioned adjacent the first end of the shaft. The second housing portion includes at least one port and a second fluid passage between the at least one port and the first fluid passage. The service port is aligned with the first fluid passage, and the service port is selectively opened to provide access to the first fluid passage from the first end of the first housing portion.

    摘要: A boom for supporting a drilling and bolting tool includes a first portion, a second portion, an actuator for moving the second portion relative to the first portion in a direction parallel to the longitudinal axis. The second portion includes an elongated shaft having a proximal end and a distal end, the proximal end supported by a shaft support for movement relative to the first portion in a direction parallel to the longitudinal axis, the distal end configured to support the drilling and bolting tool.

    摘要: A cutting assembly for a mining machine includes a mount configured to move about a first axis relative to a chassis of the mining machine and a ranging arm coupled to the mount. The ranging arm is moveable relative to the mount. The cutting assembly includes a cutting head having a housing coupled to the ranging arm. The housing is moveable relative to the ranging arm. The cutting head includes a drum supported for rotation relative to the housing about a rotational axis, a plurality of cutting bits coupled to the drum, and at least one motor supported by the housing to drive the drum about the rotational axis.
