摘要

Summary "system for determining a position of a mining machine, method of screening for a mining machine and operation of mining" is a system to determine a position of a mining machine in a mine underground, and the system Inc. Lui a emitting unit and a receiver unit.And, one of the units is positioned in fixed relationship to a wall of the mine and the other unit is mounted on the machine, in which the emitting unit transmits a coded magnetic signal that is received by the receiving unit, and the system includes, in addition, a processad Or to identify the distance and the angle between the units based on the received signal.The system uses measurement of a magnetic field of low frequency coding atravessante layer in real time and positioning 3 - d continuous mining machine. The invention also relates to a method of screening a mining machine and an operation of M. Inerau00e7u00e3o.
