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 San Antonio, Texas. This program is subject to change.


A Characterization of Gas Explosion Shockwaves for Boiler and HRSG Cleaning Applications

The purpose of this work is to experimentally measure the blast parameters of the pressure-wave technology to understand the performance and effectiveness of the process, characterize the technology for detonation and shockwave physics, and to conduct metallographic analysis of boiler tubes for potential damage during the cleaning process.


A Near-Field Ground Vibration Model for Estimation of Threshold Level of PPV for Backbreak in Surface Blasting

Backbreak is an extremely frequent phenomenon associated with blasting. The study’s focus is to predict the damages associated with blasting by the newly developed near-field, blast-induced ground vibration prediction model and also the performance of the model is evaluated for a case study.


A Successful Blasting Project near a Commercial Building

An area of 300 ft x 100 ft with 10 ft deep, adjacent to an existing commercial building was successfully excavated. The rock present at the site was gypsum layers within hard shale. The vibration levels produced from blast events were in compliance with the blasting standards.


Additive Manufacturing of Liners for Conical Shaped Charges: Practicality and Performance

Additive Manufacturing is utilized to create a series of liners with varying characteristics to test performance metrics such as depth of penetration and jet velocity of conical shaped charges. Charges were filled with the explosive C-4 and recorded with high speed video analysis. 

Additively Manufactured High Explosive Driven Plane Wave Generator

An investigation into the effectiveness of fully 3D printing both the explosive and inert component of an explosive lens type of plane wave generator.


Algorithms for Adaptive Solutions: Essential Tools for Operational Blast Optimization

Algorithms using field measurements as input information can optimize drill and blast design in open pit operations. They allow designing blasts in a much quicker way than traditional "trial and error" methods and thus are essential operational tools. Examples, combining design algorithms with measurement and drilling equipment, will be shown.


An Investigation into Variations in Blast Induced Ground Vibration with the Precision in Blast Initiation System

Blasts were conducted in a surface mine with different initiation systems and the peak particle velocities (PPV) were recorded at different distances using seismographs. Data collected for each initiation system were analyzed using scaled distance regression approach individually to understand the overlapping of the hole and actual charge per delay.


Analysis of Particle Size Distribution with Image J Programme

In this study, blasting operations efficiency was investigated in an open pit mine in Turkey. In investigation, Image J programme was used for the image processing method.


Application of ArcGIS Pro in Blast-Induced Ground Vibration Analysis in an Open Pit Copper Mine

It was observed that the ArcGIS is a great tool in finding blasting area centers, identifying structure boundaries, and visualizing blasting vibration results. This will help in controlling the blast-induced ground vibrations from the subsequent production blasts at this mine site.
