Methods and systems for efficiently operating haulers of varying sizes for transporting mined material at a mine site. The haulers can include right-sized haul trucks (RSATs). Methods and systems for efficiently using containers for mined material, including loading, handling and transporting mined material within a mine or from a mine. The containers can be carried on haulers such as movable units and moving units.

A mining machine management system includes a detection unit mounted on a mining machine that travels in a mine in which a plurality of landmarks is installed, and which detects a position of the landmark with respect to the mining machine in a non-contact manner, and a traveling control unit which corrects a current position of the mining machine based on a position of the landmark, the position having been obtained in advance, and the position of the landmark obtained by the detection unit and causes the mining machine to travel by dead reckoning navigation, and which does not use at least the position of the landmark detected by the detection unit in causing the mining machine to travel by the dead reckoning navigation, when a vehicle traveling in the mine exists around the position of the landmark detected by the detection unit.

A conveyor assembly for moving material includes a plurality of chains each defining a longitudinal axis, and a plurality of flights coupled to the at least two chains and configured to contact and move the material in a direction parallel to the longitudinal axes. Each of the plurality of flights extends along a central axis oriented oblique with respect to the longitudinal axes. Each flight includes a first portion offset from a second portion in a direction parallel to the longitudinal axes.

A control system of a mining machine controls a driving device that drives a traveling device of the mining machine. The control system includes an acceleration command value calculation unit that calculates an acceleration command value for accelerating the mining machine, a correction value calculation unit that calculates a correction value for the acceleration command value based on a first driving force component of the driving device to cause the mining machine to travel at a target traveling speed and a second driving force component of the driving device to offset a resistance component against traveling of the mining machine, an addition processing unit that calculates a correction acceleration command value by adding the acceleration command value and the correction value, and an acceleration command value output unit that outputs the correction acceleration command value to the driving device.

A feeder breaker includes a frame, a first crusher coupled to the frame and configured to receive material, a second crusher coupled to the frame, a conveyor extending between the first crusher and the second crusher configured to convey material exiting the first crusher to the second crusher, and an output conveyor configured to receive the material exiting the second crusher. The feeder breaker is also configured to allow at least a portion of material exiting the first crusher that is below a predetermined size threshold to move to the output conveyor without passing through the second crusher.

A hoist system for hoisting a conveyance from a mineshaft, comprising: a head frame mounted over the mineshaft; a hoist connected to the conveyance by an elongate flexible hoisting element so as to be operable to hoist the conveyance from the mineshaft by winding the hoisting element; an upper crash barrier located on the head frame so as to be engageable by the conveyance to prevent upward movement of the conveyance beyond the crash barrier in an overwind condition; and an upper conveyance retarder to retard upward movement of the conveyance as it approaches the crash barrier.
