摘要

The present Invention provides a method for Monitoring the Movement of a First region of a Mine Rock with a Second Region of Rock in the mine, the method comprises the steps of: providing a First device and a Second Device Marker Marker, the pr IMER Marker Device adapted to emit an electromagnetic Signal.The Second Device Marker (i) adapted to detect the strength of the electromagnetic Signal emitted by the first device (ii) Marker, and wirelessly transmit the information related to the electromagnetic Signal detected directly or indirectly to a LEC device Tor, Installing the first marker in the first Device region of RockInstall the second Marker device in the Second Region of Rock, and the monitoring of the information of the electromagnetic Signal detected in the Reader, in which, in use,The Movement of the First Rock region with respect to the Second Region of Rock indicates where the second Marker Device detects a decrease in the strength of the electromagnetic Signal emitted by the first Device Marker.
