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 papersStanding crib supports have been applied in underground mining programs to resist large roof movements and sustain high-loads. The parameter that has not been examined and is not well understood is the effect that a crib or other types of standing supp...

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.
