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.
-
1/1/1999 - Conference papersA study on the mechanics of strata behavior determined through extensive field measurements. Practical techniques for assessing roof behavior were developed along with a prototype remote controlled roof support system.
