Modeling

  1. To get reasonably accurate results, what sort of element density is required?

  2. What is the software limitation with respect to the number of blocks and the number of mining steps that could be included in a given model? What are the limitations on number of nodes and elements?

  3. Is it possible to apply tractions (i.e. internal pressures) to specific elements in my model?

  4. Is it possible to apply liners (beam elements), bolts and cables?

  5. What procedure is used for forming excavation geometry?

  6. In Examine3D, can different boundary (primary) stresses be applied in x-, y-, and z- directions?

  7. Does the "stress path" or the "loading path" of the rock have to be modeled to reasonably represent the stresses induced in the rock mass remaining around the excavations?
