Abstract: A system for monitoring conditions associated with operation of an underground machine includes a sensor that is disposed on the machine. The sensor is configured to output tri-axial acceleration data associated with the underground machine. The system also includes at least one controller that is disposed in communication with the sensor. The at least one controller is configured to evaluate the tri-axial acceleration data with at least one pre-defined criteria, and determine whether the tri-axial acceleration data is in excess of a threshold associated with the at least one pre-defined criteria based on the evaluation. The controller is also configured to record an occurrence of an abnormality in the condition associated with operation of the underground machine on the basis of whether the tri-axial acceleration data is in excess of a threshold associated with the at least one pre-defined criteria.

Abstract: A mining machine is provided. The mining machine includes a frame. The mining machine includes an engine mounted on the frame. The mining machine also includes a transmission unit operably coupled to the engine. The mining machine further includes an electric drive operably coupled to the transmission unit. The electric drive is adapted to operate as an electric motor in a first operating mode of the machine to provide electric power to the mining machine. The electric drive is also adapted to operate as an electric generator in a second operating mode of the machine to generate electric power for later use.
