Mines Systems Design Research Efforts

A three-way research program, facilitated by the U.S. Bureau of Mines Generic Institute funding, conducted by Hecla Mining Co., Spokane Research Center of the Bureau and the University of Idaho, shows that a cooperative effort to solve difficult mining problems should be considered. A five-year plan to change an overhead cut-and-fill mining system to a longwall undercut-and-fill involves more than twenty people from three organizations. The investigations will eventually include, ground stress, stress analysis, fill selection placement and compaction, ground and fill support, underhand mining and materials handling, access, ventilation, equipment selection and synthesis and operations and cost simulation.
