3/1/1999 - Conference papersTo help mitigate the potential for falls-of-ground injuries to underground stone miners, NIOSH developed the Roof Monitoring Safety System (RMSS) to aid in monitoring dangerous levels of roof beam deflection.

This video teaches the importance of proper roof scaling in underground mining to avoid injury and improve work conditions.

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 - Peer reviewed journal articlesRoof and rib conditions were observed and assessed in 33 underground stone mines. It was found that selection of the mining horizon and mine layout decisions tremendously influence ground stability.
-
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.
-
5/1/1995 - NIOSH/USBM numbered publicationsPapers presented at a USBM technology transfer seminar describe the causes of violent material failure in U.S. mines, measurement techniques for monitoring events that result in violent failure, and mitigation techniques for controlling failure.

1/1/1976 - Reports of InvestigationsExamination of several coalbeds in Walker County, Alabama, Cambria, Greene, and Fayette Counties, Pennsylvania, and Caleigh and Wyoming Counties, West Virginia, indicates that cleat orientations are similar throughout a vertical sequence of strata. Stud...
