Blasting University

Blasting University

The Blasting University is broken into two sections, Theory and Application.  

The Theory portion of the course covers the following subjects:

  • History of Explosives
  • Explosives Chemistry
  • Detonation and Shock Physics
  • Rock Breakage
  • Types of Explosives
  • Initiators
  • Geology and Rock Mechanics
  • Vibration and Airblast
  • Blasting Definitions
  • Surface Mining Methods
  • Excavation
  • Blast Types

The Application section of the course then covers how to apply the theory to practical uses.  The topics for the Application section are:

  • Blast Design
  • Drill Pad Preparation
  • Drilling
  • Priming
  • Loading
  • Gassing & Stemming
  • Timing
  • Environmental Impacts
    • Vibration
    • Airblast
    • Fume
    • Dust
    • Weather
  • Performance Measures
  • Records, Reconciliations, and QA/QC

Optional Advanced Topics Include:

  • Hot and/or Reactive Ground
    • Reactivity
    • Heat Sources
    • Inhibitors
    • High Temperature Products
  • Advanced Vibration Control
    • Signature Holes / Seed Waves
    • Site Law
    • Signature Hole Simulations
    • Timing Methods
    • Monitoring Locations
  • Muckpile Shaping
  • Ore Dilution / Coal Damage – Through Seam Blasting

Rush Valley Plant Tour and Explosive Demonstrations:

Students will have the opportunity to follow the process of emulsion manufacturing at the Rush Valley Plant.  This will give them a deeper understanding of the raw materials and the variables involved with the manufacture of ammonium nitrate based emulsions.

The explosive demonstrations are designed to give the students a greater understanding of the power of explosives.  Many times personnel that work with explosives have not had the opportunity to witness unconfined detonation of the products that they work with on a daily basis.  There is a significant difference between witnessing 10 pounds of ANFO detonating, fully confined in rock, versus detonating out in open air. The goal of the demonstrations is not to instill fear into the students, but to serve as a reminder that the items they work with or around are powerful and destructive.
