Abstract
The hybrid computer facility at the University of Minnesota was designed to analyze three-dimensional pillar stresses in coal mines. This report describes recent improvements and applications that include expansion of the capability to model nonlinear seam behavior, installation of a color video output display monitor, and further development of software capabilities. To demonstrate the capability of the system, the influence of nonlinear seam behavior response on the occurrence of coal mine bumps was fully investigated. Then the effect of improper mining sequence on bump occurrences was demonstrated. Also, the system was applied to the analysis of a series of practical coal mine problems. Mines in three coal seams were analyzed to investigate the parameters that contribute to the occurrence of coal mine bumps.
