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.
-
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.
-
11/1/1998 - Conference papersTo provide a better understanding of the mechanics of strata deformation, the authors have collected and reviewed measurements of convergence and stress in one western U.S. mine and have completed modeling for two typical pillar-pulling plans.
-
8/1/1998 - Conference papersThis paper presents the results of a case study conducted in a two-entry gateroad in a coal mine where excessive roof deformation and bolt loading resulted in failure of many roof supports.
-
8/1/1997 - Conference papersA method to assist in the evaluation and selection of roof bolts using in situ measurements of roof bolt loading has been developed by researchers of the Spokane Research Center, National Institute for Occupational Safety and Health.
