The mine truck includes a frame; a container for carrying payload supported by the frame; and at least one sensor, the at least one sensor delivering signals being dependent on a force acting on the mine truck. The method includes for at least a first position of the frame, estimating a level of stress that said at least a first position is subjected to in response to a force acting on the mine truck, wherein said at least a first position is a position being different from the position of said at least one sensor; and estimating said level of stress utilising a model representation of the level of stress for said at least a first position wherein said model representation output said estimated level of stress utilising sensor signals from said at least one sensor as input signals.

A mined material transport vehicle includes: a vehicle main body capable of moving forward and rearward; and a loading platform provided on the vehicle main body, wherein the loading platform includes: a conveyor provided on the vehicle main body and having a conveying surface capable of conveying a mined material in a conveying direction extending in a forward-rearward directions; a pair of movable flaps that extend in the conveying direction on both sides in a vehicle width direction of the conveying surface, form a storage space together with the conveying surface, and are rotatable about lateral axial lines extending in the conveying direction; and lateral cylinders for rotating the movable flaps about the lateral axial lines.

Disclosed are vehicles used in transporting coarse ore in a mine and systems using the same. The vehicles include a drive mechanism for moving the vehicle along a surface; an inclinable conveyor positioned atop the drive mechanism for moving the coarse ore from a loading position to a discharge position; and vertically extending walls positioned along the longitudinal sides of the conveyor. The loading position of the conveyor being offset from the vertically extending walls and the discharge position of the conveyor extends beyond the vertically extending walls so that one vehicle can be positioned with respect to another to form a continuous walled conveyor. The vehicles and systems described herein do not require rails, so they can be manoeuvered within a mine to form a network from the mine face to a coarse ore unloading area.

The specification discloses a driverless haulage vehicle (10,32,43,44,45) for use within an underground mining operation including a unitary support chassis (11) having a first end section (15), a second end section (16) and a central section (50) located between said first and said second end sections (15,16), haulage vehicle transport means (51) including a first wheel assembly (52), associated with and supporting the first end section (15), a second wheel assembly (53) associated with and supporting said second end section (16) of the unitary support chassis (11), and a third wheel assembly (54) associated with and supporting the central section (50) of the unitary support chassis (11), steerage means (55) carried on said driverless haulage vehicle (10,32,43,44,45) for directing said vehicle along a transport path with an underground mine, the steerage means (55) including said first wheel assembly (52) and said second wheel assembly (53), said steerage means (55) further including a sensor set from which sensor data is generated representing internal status of the driverless haulage vehicle (10,32,43,44,45), and/or environmental status within which the driverless haulage vehicle (10,32,43,44,45) is operating, and controllable activators (27) to control steering movements of said first wheel assembly (52) and said second wheel assembly (53) whereby driving steering, wheels (13) of the first wheel assembly (52) are directed oppositely to wheels (13) of the second wheel assembly (53).

A mining system includes: a first tunnel that reaches a dump site and includes a first road surface; a second tunnel that crosses the first tunnel, reaches a mining site, and includes a second road surface positioned above the first road surface; a frame that includes a lower surface provided above the first road surface of the first tunnel and forming a transport passage between the first road surface and the lower surface and an upper surface forming a work road surface, on which a loading machine operates, together with the second road surface; and a moving vehicle that is capable of traveling on the first road surface and is capable of passing through the transport passage.

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. The method includes determining whether a relocation has occurred. The method includes, when the relocation has occurred: determining a cut end time. The method includes 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.

The invention discloses a brakeable transportation ore cart for mine mineral transportation, which comprises a base. Hydraulic rods are symmetrically fixed to the left and right ends of the base. The hydraulic rod is provided with a support beam for installing a motor. The motor is mounted on the beam. A moving first gear is mounted on the beam, and a hopper is rotatably installed through a rotating shaft. A second gear meshing with the first gear is fixedly mounted on the rotating shaft. A telescopic plate supported by a first spring is provided at the bottom of the hopper. Drive the hydraulic rod to make the entire hopper rise, and the third guide rod in contact with the lower end of the hopper moves upward along the sliding groove under the action of the left-right symmetrical fourth spring, thereby driving the fourth guide rod to move upward and the fourth guide rod. The fifth gear connected at the end is moved upward. Under the action of the third rack and the fifth gear meshing with each other, the fifth gear moves counterclockwise to drive the fourth gear meshed with the fifth gear to move downward.
