8/1/2001 - Conference papersThe location and time of 2,007 microseismic emissions from a limestone mine were compared with mine face development and mine layout characteristics. The occurrence of roof failure zones appears to be associated with mine plan characteristics.
-
8/1/2001 - Conference papersThe Support Technology Optimization Program (STOP) was updated to Version 2.3. This paper describes the additional features: including uncontrolled convergence into the design requirements for standing roof supports; the addition of design procedures fo...

8/1/2001 - Conference papersA historic overview of the role of mobile roof support (MRS) technologies in improving stability and worker safety is presented along with field evaluations of the MRS load rate monitoring device and other remote deformation-monitoring techniques.
-
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.
-
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.
