1/1/1999 - Conference papersVarious 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.

8/1/1998 - Conference papersA comprehensive survey of mine seismicity a rock bursting during development of two sublevels at the Lucky Friday Mine, Mullan, ID, was conducted to better define rock failure mechanisms and sources of ground control hazards.

8/1/1997 - Conference papersResearchers from private industry and NIOSH have studied mechanisms of violent failure and have identified individual factors that contribute to coal bumps. They initiated a comprehensive study to develop tools for assessing coal bump potential.

3/1/1997 - Conference papersSudden, violent failures of rock around mine openings influence access, ventilation, and safety in both hard-rock and coal mines. The authors initiated a comprehensive study to develop predictive tools for assessing potential rock failure.

1/1/1997 - Conference papersRock masses in deep-level mines are subject to high stresses, which can result in unexpected failure of rock into mined-out openings. Personnel from two research centers of the former U.S. Bureau of Mines, Spokane and Twin Cities, investigated a rock b...

8/1/1990 - Conference papersThis paper describes research designed to quantify the behavior of a particular size abutment pillar prone to burst or bump (local terminology). This research has attempted to construct the stress and convergence profiles of the pillar.
