Claim 4:
5. A method of installing a system of devices in a movable ground region of a mine, the method comprising:
providing a plurality of devices, each of which comprises:
one or more sensors configured to sense one or more parameters useful in determining movement and/or the potential for movement in a movable ground region of a mine and output the parameter as sensor data;
a radio transmitter configured to transmit sensor data to another of the plurality of devices;
a radio receiver configured to receive sensor data from another of the plurality of devices;
a power source configured to power the radio transmitter and the radio receiver; and
a housing configured to protect the power source, the radio transmitter and the radio receiver, and enclose or be integral with the sensor,
wherein:
the plurality of devices form a mesh network across which sensor data is propagated via the radio transmitters and the radio receivers; and
one of the plurality of devices is configured to transmit sensor data to another of the plurality of devices when there is a change, or an appreciable change in sensor data compared to an earlier point in time; and

burying the plurality of devices within the movable ground region.
