Monitoring of longwall linings in the longwall excavation system

摘要

The subject of the notification is a monitoring device and a method of monitoring a wall extraction system with multiple wall enclosures, each wall enclosure containing a pressure sensor to determine the levels of wall enclosure pressure during the monitoring cycle. Pressure data are obtained for many wall enclosures. This data shall contain the pressure information for each wall housing of the many wall enclosures in the monitoring cycle and shall be analysed for determination,whether there was an error in the first type of pressure during the monitoring cycle for each wall housing. The number of errors shall be generated, which shall mean the number of wall enclosures where a first type pressure error has been detected during the monitoring cycle. Upon finding that the number of errors exceeds the alert threshold, a notification shall be generated.
