• Description:
  A geomechanical numerical modeling research project is being conducted for the Stillwater Mine located in Nye, Montana. The project involves identifying potential ground control problems and exploring various methods of modeling the behavior of the rock, with objectives of improving underground safety and facilitating optimum support design. During the preliminary modeling stage of the project, it was determined using continuum-based approaches that the discontinuities can control the behavior of the rock; the data collection system at the mine was subsequently adjusted to provide more information about the rock joints. A parametric study of possible underground conditions at one specific site was then conducted using discrete element methods. The results compare well with a rough analysis of the conditions. A discussion of the strengths and limitations of the methods employed and the significance of the results is included. [Description provided by NIOSH]
