The technical sessions will showcase the latest technological advances. Whether you're a blaster in the field or a supervisor, you'll find this an informative, enjoyable event. The following is a preliminary list of papers which will be presented in Denver, Colo. This program is subject to change.

New: Spanish translation services now available for all technical sessions on Monday and Tuesday. 


Accidental Activation of an Emergency Rocket Flare and Evaluation of Ignition Mechanism Designs

We describe an engineering investigation of an accident involving a rocket parachute flare, and examine the various mechanisms by which these emergency signaling devices are ignited.


A Method to Measure Detonation Front Curvature of Emulsion Explosives

This paper suggest a method measure the detonation front curvature and the velocity of detonation of explosives. The purpose for this is to increase the understanding of the detonation properties of emulsion explosives as used in many blasting operations around the world.

A Practical Guide for the Blasting of Armour Stone or Riprap

Industry best practice guidelines for the blasting of riprap or armour stone.


AN Railcar Derailed Debris Collection – Data Analysis Update

A complete data analysis was completed on test data collected from an AN Railcar detonation. The analysis included an assessment of both the debris data and airblast data resulting from the test. This paper is meant to serve as a summary of the analysis and findings from the debris collection.

Analysis of Sympathetic Detonation in Detonating Cord

Application of Geostatistical Tools in Measurement While Drilling to Assess Geotechnical Rock Conditions in Sublevel Caving

Development of a geotechnical rock condition block model and a predicting risk of blasthole collapse model with reference to MWD records and application of geoestatistical tools to estimate values in all the points of the studied domain and not only in the sampled points.


Assessment of Post-Blast Damage Zones in Tunneling Operations Through MWD and Machine Learning

The overbreak of the remaining rock mass in tunnel blasting has been analyzed in the light of MWD records, with the purpose of developing a prediction model of over- and under-excavation depths from blasting.

Attracting and Engaging the New Generations: An ISEE Student Chapter Case Study

How do the extractive and construction industries gain the interest of the younger generations and integrate them into the industry? The Virginia Tech Student Chapter of the International Society of Explosives Engineers handled this issue in recruitment efforts and event planning from 2017-2019.

Bingham Canyon Mine-Blasting Through and Next to Active Underground

The implementation of blasting practices and designs to collapse sections of an active underground while maintaining vibration limits below levels to protect workings that remain in use.


Blast Optimization Using Both the Multiple Blasthole Fragmentation (MBF) and Multiple Seed Waveforms (MSW) Models at an Open Pit Metal Mine

A blast optimization project was carried out at an Open Pit Mine in the USA using the MBF Model and the MSW blast vibration model. The MBF and MSW are each an integral part of the blast optimization tool. Various scenarios using different explosives, hole delays, blast patterns were modeled.

Blasting Mitigation Measures Used to Control a Highwall Failure Risk

Blasting mitigation measures were used to control a highwall failure risk. This consisted in optimizing the blasting parameters which would not induce the highwall failure and in evaluating the rock mass response to blasting by using radar. The risk management plan was successful because blasting didn't induce highwall failure.
