7/1/2001 - Conference papersInstrumented cable bolts were used in conjunction with existing ground control to monitor rock mass loads at various field sites. By monitoring rock mass load and displacement, more effective ground support can be selected and installed.
-
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.
-
8/1/2000 - Conference papersThis paper addresses a deficit in pillar loading research by exploring the accuracy of empirical abutment load calculations using insight provided by an elastic overburden model, a laminated overburden model and field observations.
-
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.
-
8/1/1999 - Conference papersThis paper discusses a design methodology for standing secondary tailgate supports, using the performance characteristics generated in the NIOSH Mine Roof Simulator (MRS) to match load characteristics of various supports to ground reaction behavior.
-
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.
-
3/1/1999 - Conference papersRecently, powerful design methods have emerged from analysis of large data bases of real-world pillar successes and failures. In the process, our understanding of pillar mechanics has been greatly enriched.
-
1/1/1999 - Conference papersThis paper examines current design practices for stone mines and discusses issues for safe mine layouts so that a rational first approach towards balancing the demands for increased production can be weighed against increased risk to worker safety.
