  • Method for performing wedge analysis for assessing wedge instabilities in underground openings
    Patent number: 6757642
    Abstract: A method is provided for performing wedge analysis for assessing wedge occurrence and instability in underground openings, such as mines, caves, and the like. The method scales full-span wedge predictions, accounting for both occurrence and instability potential of possible wedge geometries. The method also generates predictions for wedge failure potential and support demand to result in more economical support design for wedges.
