AUTONOMOUS MINING SYSTEM BASED ON REAL-TIME DIGITAL VIDEO COMMUNICATION THAT USES ETHERNET AND OPTICAL TECHNOLOGIES
An autonomous mining system includes a real-time digital video transmission sub-system configured to obtain video streams from underground, and transfer the video streams to a control center located above ground; and an exploration and maintenance sub-system located underground, and configured to extract a resource and bring the resource to the surface, based exclusively on commands received from the control center through the real-time digital video transmission sub-system.
CUTTER HEAD FOR MINING MACHINE
A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.

Milling Machine And Method For Operating A Milling Machine
The invention relates to a milling machine having a replaceable milling drum, different types of milling drums being capable of being associated with the milling machine; and having a control unit for controlling the milling machine, machine parameters of the milling machine being settable by way of the control unit. Provision is made that the milling machine has associated with it at least one means that is designed to detect at least one characteristic feature of the milling drum; that the at least one means is connected to the control unit; and that the control unit is designed to specify for at least one machine parameter, indirectly or directly from the characteristic feature, a value to be set, and/or a setting range. The invention further relates to a corresponding milling drum and to a corresponding method. The milling machine, milling drum, and method allow the selection of machine parameters for operation of the milling machine to be simplified.

ROTARY BORING MINING MACHINE INERTIAL STEERING SYSTEM
A mining system with an inertial guidance system configured to enable precise excavation of geological material without a need to advance a survey line over a long distance and/or nonlinear excavation path, thereby maximizing productivity of the mind by minimizing a width of un-mined material necessary for support between adjacent excavation paths and minimizing equipment downtime.

Controlling an output of a mining system
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.

Fiber optic shape sensing adapted to cutter module of highwall miner
A system for determining the position and orientation of a cutter module relative to a frame of a highwall miner is provided. The cutter module is attached to the highwall miner by a string of push beams and moveable relative to the highwall miner. A reel is rotatably mounted to the highwall miner frame and configured to feed out a hose chain that supplies fluid to the cutter module. A fiber optic shape sensing system is associated with the cutter module is configured to receive strain information from the fiber bundle and compute the location of at least one position of the fiber bundle that is associated with the cutter module relative to the reference frame.
