Abstract: A mining vehicle control system includes a detection unit configured to determine a proximity of a monitored mining vehicle to a first mining vehicle and a controller configured to determine first protection lines that linearly project from the first mining vehicle and second protection lines that linearly project from the monitored mining vehicle. The first protection lines are determined based on a moving speed of the first mining vehicle. The second protection lines are determined based on a moving speed of the monitored mining vehicle. The controller is configured to direct the first mining vehicle to change movement of the first mining vehicle responsive to intersection of one or more of the first protection lines with one or more of the second protection lines.

Abstract: A system includes a first vehicle having an emitter configured to emit a high RF signal synchronously with at least one EM pulse, and a receiver unit located remote from the first vehicle. The receiver unit includes a magnetic field receiver, an RF transceiver, and a processing module coupled to the RF transceiver and the magnetic field receiver. The receiver unit is configured to receive the high RF signal and the at least one EM pulse from the first vehicle and to determine a proximity of the first vehicle to the receiver unit.

Abstract: A drill sensor system of a drilling system and method for generating navigation data for the drilling system uses both a radar sensor and a magnetometer disposed in and/or coupled to a drill rod assembly having a drill head configured to drill a hole beneath a surface. The radar sensor emits an electromagnetic wave and obtains an echo of the electromagnetic wave in order to generate radar data representative of one or more objects beneath the surface. The magnetometer sensor generates magnetometer data representative of an orientation of the magnetometer sensor relative to a magnetic field. The radar data and magnetometer data can be used to generate images for navigating the drill rod assembly during drilling of the hole.
