7/1/2002 - Conference papersA case study of a rock burst was conducted as part of a project to reduce rock burst hazards being undertaken by the Spokane Research Laboratory (SRL) of the National Institute for Occupational Safety and Health (NIOSH).
-
2/1/2002 - Conference papersNIOSH has developed an automated PC-based seismic event (induced earthquake) monitoring system for use in mine ground control studies. This paper describes system design philosophy, hardware/software components, installation examples, and results.
-
2/1/2002 - Conference papersSixty years of rockbursting in the Coeur d'Alene district has taught painful lessons and led to practical advances in controlling rockburst hazards. This paper summarizes those lessons, concentrating on practical measures to reduce hazards.
-
8/1/2001 - Conference papersInstrumented cable bolts developed at NIOSH's Spokane Research Laboratory were used in conjunction with existing ground control systems to monitor rock mass loads at Tg Soda Ash's trona mine in Granger, WY.
-
6/1/2001 - Conference papersNIOSH has developed an entire toolbox of computer programs that have been effectively transferred to the mining community.
-
3/1/2000 - Conference papersInstrumented cable bolts developed at the Spokane Research Laboratory of the National Institute for Occupational Safety and Health were used in conjunction with existing ground control to monitor rock mass loads at various field sites.
-
8/1/1998 - Conference papersGround conditions at 10 Australian longwall mines and two room-and-pillar mines are compared with an extensive database from U.S. mines. Comparisons include the Coal Mine Roof Rating, roof support, pillar design, and ground control conditions.
-
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.
-
1/1/1998 - Conference papersUnusual circumstances sometimes require a longwall retreat into/through a previously driven room, with the potential for failures and roof fall hazards. To determine the failure factors, NIOSH compiled an international database of 130 case histories.
