Abstract

The invention provides a system for monitoring movement of a rock face which includes: - a plurality of sensors, each of which is adapted to detect movement of the rock face and, on detection of rock movement, to generate a signal; - a receiver for receiving signals generated by the sensors; - a communication link which links each of the sensors to the receiver and along which a signal is transmitted to the receiver; and - an warning device which is actuable to generate an alarm response to at least are signal received by the receiver.
