Monitoring of longwall linings in the longwall excavation system
Abstract
The subject of the application is a monitoring device and a method for monitoring a longwall mining system having a plurality of wall casings, each wall housing comprising a pressure sensor for determining the pressure levels of the wall housing during the monitoring cycle. Pressure data is obtained for many wall cases. This data provides pressure information for each wall housing from a plurality of longwall casings in the monitoring cycle and is analyzed to determine if a first type of pressure error occurred during each monitoring cycle for each wall housing. The number of errors is generated, which means the number of wall enclosures in which the first type of pressure error was detected during the monitoring cycle. After finding
