  • obtaining, by a processor, pressure data for the plurality of roof supports, the pressure data including pressure information for each roof support of the plurality of roof supports over a monitoring cycle;

    analyzing the pressure data, by the processor, to determine whether, for each roof support, a first type of pressure failure occurred during the monitoring cycle;

    generating a fault quantity representing a number of roof supports determined to have had the first type of pressure failure occur during the monitoring cycle; and

    generating an alert upon determining that the fault quantity exceeds an alert threshold.
