US 9,739,148 B2 · Roof support monitoring for longwall system

Abstract

A monitoring device and method for monitoring a longwall mining system having a plurality of roof supports, each roof support including a pressure sensor to determine pressure levels of the roof support during a monitoring cycle. Pressure data is obtained for the plurality of roof supports. The pressure data includes pressure information for each roof support of the plurality of roof supports over a monitoring cycle. The pressure data is analyzed to determine, for each roof support, whether a first type pressure failure occurred during the monitoring cycle. A fault quantity is generated that represents the number of roof supports determined to have had the first type of pressure failure occur during the monitoring cycle. An alert is generated upon determining that the fault quantity exceeds an alert threshold.

Dependent claims

A method of monitoring a plurality of roof supports of a longwall mining system, the method comprising:

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.

A monitoring device for a longwall mining system having a plurality of roof supports, each roof support including a pressure sensor to determine pressure levels of the roof support during a monitoring cycle, the monitoring device comprising:

a monitoring module implemented on a processor in communication with the plurality of roof supports to receive pressure data including the determined pressure levels, the processor including:
an analysis module configured to analyze the pressure data and to determine whether, for each roof support, a first type of pressure failure occurred during the monitoring cycle;
a tally module configured to generate 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
