6/1/2001 - Conference papersA study is described where information was collected at 37 coal mines on roof falls and other geotechnical, mining, geologic, and roof bolting factors. A statistical analysis was conducted on the data with roof fall rate as the outcome variable.
-
This paper presents an overview of the most significant ground control hazards facing today's mineworkers, as well as best practices to reduce these risks.
-
4/1/2000 - Conference papersResearchers are investigating the physical properties of cable bolts by replacing the conventional king wire with a modified king wire on which strain gauges have been installed.
-
3/1/2000 - Conference papersA NIOSH study of the time-dependent response of rock stressed along weakness planes with the objective to improve mine safety by reducing the number of roof falls that cause injuries and fatalities to miners.
-
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.
-
8/1/1998 - Conference papersThis paper describes the potential adaption of systems such as interferometric synthetic aperture radar, imaging spectroscopy, and time-domain reflectometry, to slope monitoring and design.
-
8/1/1998 - Conference papersBased on field investigations and a U.S. coal mines database containing 12 mines and 639 roof falls, NIOSH determines the factors that influence intersection instability and provides guidelines for the safe excavation and support of intersections.
-
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.
