Theoretical analysis of bump and airblast events associated with coal mining under strong roofs
This investigation was conducted to study the bump and airblast problems associated with delayed caving of competent longwall roofs. The roofs were modeled as elastic beams on continuous elastic foundations subject to exponentially distributed abutment stress. Elastic beam theory was applied to deve...
