Questions and Answers

What factors are considered when optimizing a blast design?

  • Orebody depth and width
  • Rock hardness and color
  • Burden and spacing, explosive types, timing and sequencing (correct)
  • Drilling speed and efficiency

    • How does an optimized blast design impact excavation stability?

  • Increases stability by reducing orepass hang-ups
  • Increases stability by reducing mucking unit wear (correct)
  • Has no impact on stability
  • Decreases stability due to excessive fragmentation

    • What is the purpose of adjusting blast patterns in different stope geometries?

  • To increase drilling access
  • To reduce the need for explosive types
  • To enhance the color of the orebody
  • To determine the optimal design based on rock mass conditions (correct)
