摘要： A guide shoe for a mining machine includes an elongated shoe body, a slot, an insert coupled to the shoe body, and a retainer secured to the shoe body. The shoe body includes a first end, a second end, a first wall, and a second wall. The slot extends between the first end and the second end along a slot axis, and the slot extends along the first wall and the second wall. The insert is positioned between the shoe body and the slot axis and extends along at least a portion of a perimeter of a cross-section of the slot. The insert includes an end positioned adjacent the first end of the shoe body. The retainer abuts the end of the insert to secure the insert against movement relative to the shoe body in a direction parallel to the slot axis.

摘要： A conveyor chain includes a first link, a second link, and a coupler link. The first link includes a first sprocket-engaging portion and a second sprocket-engaging portion, each protruding laterally away from one another. The second link includes a first sprocket-engaging portion and a second sprocket-engaging portion, each protruding laterally away from one another. The coupler link couples the first link to the second link, and the coupler link is positioned laterally between the first sprocket-engaging portion and the second sprocket-engaging portion of each link. The coupler link includes a first joint pivotably coupled to the first link and a second joint pivotably coupled to the second link. The first joint permits pivoting movement of the first link about a plurality of axes, and the second joint permits pivoting movement of the second link about a plurality of axes.

摘要： Methods and systems for evaluating underground road conditions using accelerometers. One system includes an electronic processor that receives sensor data from an accelerometer and location data of a mining machine operating within a mining environment. The electronic processor determines, based on the sensor data, a first data point when acceleration in a first direction exceeds a predetermined first threshold based on the sensor data, and determines a second data point when acceleration in a second direction opposite the first direction exceeds a predetermined second threshold. The electronic processor also determines a location of a road condition associated with the first data point and the second data point based on the location data and takes at least one automatic action to correct the road condition.

摘要： A mining machine including a chassis, an actuator, a cutter drum supported by the chassis, the cutter drum driven by the actuator, a cutter bit coupled to the cutter drum, and a controller. The controller includes a processor and memory and is configured to measure a characteristic of the actuator, determine the cutter bit is worn based on the measured characteristic of the actuator, and output a signal when the cutter bit is determined to be worn.

摘要： Systems and methods for monitoring extraction height and volume of material extracted for a mining machine. The method includes operating the machine using a shearing motion at a plurality of cut locations. The method includes receiving boom height data and power consumption data. The method includes determining a cut start time, based on a conveyor motor start time, and a conveyor motor stop time. The method includes determining whether a relocation has occurred. The method includes, when the relocation has occurred: determining a cut end time based on conveyor motor stop time and the relocation; and storing, in a memory, the cut start and end time, and the boom height and power consumption data. The method includes adjusting the operation of the mining machine based on the cut start and end time, and the boom height and power consumption data for at least one of the cut locations.

摘要： A mining shuttle car that trams on underground roadways includes a conveyor system and an operator's compartment adjacent to the conveyor system. The operator's compartment includes a rotatable seat and a control station. The operator's seat module is coupled to one or more joysticks that control the car, and the operator's seat module and the control station are mounted on a rotatable platform so as to be rotatable as a unit between a plurality of secured positions for operating the mining shuttle car. Forward movement of the joystick control relative to the seat steers the shuttle car about a point in front of the seat, and rearward movement of the joystick control relative to the seat steers the shuttle car about a point behind the seat. Forward and rearward movement of one of the joysticks steers the mining shuttle car in the same manner regardless of the rotational position of the rotational position of the seat.

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： Systems and methods are provided for detecting face creep of a longwall mining system. The system includes a detection device mounted in a maingate roadway and coupled to the detection device. The controller determines the position of the beam stage loader-armored face conveyor interface based on a signal from the first indicator device, determines a position of a maingate line based on a signal from a maingate indicator device, and determines a position of a belt conveyor based on a signal from a belt conveyor indicator device. The controller further determines a first distance between the position of the beam stage loader-armored face conveyor interface and a maingate line, and a second distance between the position of the belt conveyor and the maingate line. The controller generates an indication of face creep based on the first distance and the second distance.

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.
