  1. 4. what property could cause removable blocks to be safe against sliding
  2. 6. blocks that are unable to come out of the excavation and are irrelevant to stability
  3. 7. the value in the block code used to denote the block is above a joint
  4. 9. how does the upper hemisphere compared to the same joint sets plotted in lower hemisphere
  5. 10. the man who developed the system to determine whether the system will fail along the intact rock or along the discontinuity
  6. 12. how the discontinuity is visualized on a polar graph
  7. 13. a block that if removed, compromises the stability of the structure

  1. 1. A block is finite if the joint pyramid and the excavation pyramid have no ____
  2. 2. the value in the block code used to denote the block is above a joint
  3. 3. how the intact rock is visualized on a polar graph
  4. 5. blocks that finite but "locked-in" the excavation
  5. 8. the man the theorem of removability is named after that determines if a block can be removed from the excavation or not
  6. 11. the hemisphere used for block theory analysis
