Mine Pressure Monitoring System Based on Automatic Acquisition of Working Face Feeds

The existing mine pressure monitoring system has already realised online continuous monitoring of the working face stent resistance, roadway roof off-loading and anchor rod/rope working resistance. However, the mine pressure monitoring information of the working face is only the stent resistance and monitoring time, and there is no information on the working face advance. When analysing the mine pressure data, no accurate analysis can be made due to the lack of measurement point locations. Mine pressure data analysis combined with the working face progress information is the basis for improving the safe and efficient mining and intelligent level of the comprehensive mining working face. This system adopts UWB (Ultra-Wide Band) technology and SDS-TWR (Symmetric Double-Sided Two-Way Ranging) positioning algorithm, takes UWB positioning base station as the core, installs positioning tags in the working face end bracket for information collection, and uploads the data to the supremacy computer for coordinate solving via Ethernet. The data is uploaded to the host computer via Ethernet for coordinate solving, automatically collects the working face advancement data, and provides location information for mine pressure monitoring. The application results show that the system operates normally, and can collect real-time working face advance information and monitor mine pressure data with good application effect.
