• Description:
  The overall objective of this grant was to reduce the injuries and fatalities associated with ground falls in underground mines by developing a state-of-the-art stability mapping system which tightly integrates geo- mechanical stress analysis and geological mapping. The primary output of this grant is the Integrated Stability Mapping System (ISMS) software program which takes the site-specific mining plan, geology, and stability criteria as input and produces a map of the mine showing the relative stability index of the different mining areas. The calculated stability index in this program includes the appropriate geologic influences at the mine along with the geo-mechanical stress effects from overburden depth, pillar design, adjacent seams, stream valleys and other user-defined influences. This final stability index can be used for mine planning and support design in order to reduce the hazards of ground falls. The Integrated Stability Mapping System (ISMS) is implemented inside the de-facto standard drawing environment, AutoCAD, and is compatible with the widely used geologic modeling software, SurvCADD. This compatibility allows the user to access numerous existing geologic data and mining information from present mine maps easily and directly. ISMS is also integrated with the LaModel stress analysis program, a boundary element method which can produce realistic and accurate, stress and displacement analysis using the true topography and the actual pillar plan. In order to validate the ISMS program, two case studies are performed. These initial case studies allowed the program to be checked for coding errors and calculation accuracy, and demonstrated the functionalities and usefulness of the system. In the case studies, the composite stability index was also compared with field observations, and a good correlation was found, although only a limited number of influence factors had been considered. Ultimately, it is shown that the stability mapping system provides mining engineers with the ability to perform comprehensive, rapid and accurate multiple-factor stability mapping analysis. The resultant stability map can be a valuable guide to safer support designing and better mine planning, and ultimately increase the safety of mine design and reduce the injuries and fatalities associated with ground falls in underground mines.
