Roof support monitoring for longwall system |
摘要 |
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. 6822557_1 (GHMatters) P100832.AU LYNT |
