Analysis and redesign of mine bearing plates

This paper discusses optimization analysis performed on a recently patented rock bolt mine bearing plate design. Mine bearing plates are used to help secure the ceilings of underground mines.The improved mine bearing plate was to conform to the mine ceiling when in use. Due to anticipated plastic behavior, the analysis required material properties in that region of the stress strain curve. Finite element analysis was performed on the plate in order to meet strength and flexibility requirements. Using the finite element program Ansys, various configurations of material type and thickness were analyzed in a loading scenario which simulated the American Society for Testing and Materials (ASTM) designation F432.Plates which met the ASTM criteria were reviewed and the optimized design was selected.
