MINING MACHINE POSITION TRACKING AND MAPPING

摘要

A system for determining a position of a mining machine in an underground mine, the system including an emitter unit and a receiver unit, one of the units being positioned in fixed relation to a mine wall and the other unit being mounted relative to the machine, wherein the emitter unit transmits a coded magnetic signal that is received by the receiver unit, the system further including a processor to identify the distance and relative angle between the units based on the received signal. The system utilizes ranging of a through- strata coded low frequency magnetic field for real time and continuous 3-D positioning of the mining machine. The invention also relates to a method of tracking a mining machine and a mining operation.
