Abstract
The U.S. Bureau of Mines (USBM) has developed a computer-assisted Ground Control Management System (GCMS) for near real-time evaluation of underground coal mine ground conditions. The GCMS combines existing mine monitoring system and sensor technology with automated computer analysis techniques to enhance the acquisition, analysis, and display of geostructural data. The GCMS, which combines mine structure data with other information, such as geologic conditions and mine layout, has provided information on mining-induced stress transfer and pressure buildup associated with several ground control events. Real-time collection, processing, and analysis of mine structure and shield pressure information has proven to be an effective method for assessing near-face ground conditions while mining progresses. The GCMS provides the mine operator with information to rapidly identify and manage potentially hazardous ground conditions while mining is in progress.
