• 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.
• Role of Fault Slip on Mechanisms of Rock Burst Damage, Lucky Friday Mine, Idaho, USA
  1/1/1999 - Conference papers
  Various methods of monitoring slip movements on bedding planes, as well as examination of rock burst damage in stopes, suggest that many rock bursts in the Lucky Friday Mine are closely associated with these movements.
• A Hybrid Statistical-Analytical Method for assessing Violent Failure in U.S. Coal Mines
  1/1/1999 - Information Circulars
