• Differential Wall Rock Movements Associated with Rock Bursts, Lucky Friday Mine, Coeur d'Alene Mining District, Idaho, USA
  6/1/1999 - Conference papers
  Various methods of monitoring slip movements on bedding planes, as well as examination of rock burst damage in stopes, suggests that rock bursts in the Lucky Friday Miner are closely associated with these movements.
• Characterization of Gas Flow in Longwall Gobs: Pittsburgh Coalbed, PA
