7/1/2010 - Conference papersInstrumented test sites were installed in the tailgates of two western longwall operations; results of the support performance and ground reaction are presented in terms of developed support loads and displacements and tailgate entry convergence.
-
7/1/2008 - Conference papersIn this NIOSH study to optimize standing roof support design, ground response curves were developed for longwall tailgate conditions from numerical models of Pittsburgh Coal Seam geology.
-
6/1/2006 - Conference papersThis paper presents the results of a study into the ground response around tailgate entries using numerical models. The potential exists to develop site-specific tailgate design curves by combining model results with field observations.
-
8/1/2005 - Conference papersThe conclusion drawn from this study was that standing supports do not have sufficient capacity to control main roof or floor loading or prevent the resulting convergence of the tailgate entry.
-
2/1/2005 - Conference papersWestern mines have had limited choices for standing support. This paper compares the performance characteristics of various support systems.
-
8/1/2003 - Conference papersPumpable roof supports provide an alternative longwall tailgate roof support and have grown in usage recently. Despite the success of these supports, questions remain regarding critical design issues for optimizing the use of this technology.
-
6/1/2003 - Conference papersThe primary objective of the paper will be to discuss strata mechanics and ways in which the support and strata interaction can be evaluated to provide an optimized secondary support design, particularly standing support systems, for longwall tailgates.
-
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.
