Abstract
West Virginia University has developed a stability mapping system which is designed to allow the mining engineer to effectively combine the mine geologic characteristics, structural features and stress influences into an integrated stability map for use in support design and mine planning. This stability mapping system is built upon the popular AutoCAD/SurvCADD platform for inputting the geologic and structural characteristics, and integrates both the boundary element program LaModel for determining the stress influences and the Coal Mine Roof Rating (CMRR) (originally developed by the USBM/NIOSH) for quantifying the geo-mechanical stability of the roof rock. This paper describes the stability mapping system and details the application of the system to a multiple-seam longwall coal mine.
