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 Orlando, Fla. This program is subject to change.

 

A New Approach to 3D Modulation of Blast Free Faces

This document investigates a newly developed technique with the objective of improving terrain triangulation models, mainly blast free faces. The result and the quality of the algorithm demonstrates the improvement on the triangulation quality, reducing errors in the calculation of over/under burden and free face volumes and cavities.

 

A New Blast Vibrations Analysis Methodology

This article proposes an improvement in estimation of the magnitude of the vibrations resulting from rock blasting methodologies. This methodology combines the usage of empirical vibration attenuation laws with terrain discretization techniques using Voronoi’s decomposition. Comparing with present procedures, this methodology ensures a better estimation of the vibration phenomena.

 

A Study of Overall Cost Optimization in Underground Mining

The goal of reduction of overall cost, increasing the mining efficiency and controlling the blasting results in underground mining can be achieved through integration of advanced technology and management, featuring optimization of blasting design and organize the program correctly.

 

A Tolerable Risk Criteria – What Is Safe Enough?

A Tolerable Risk Criteria is needed to more fully use the quantitative risk analysis (QRA) tool known in the commercial explosive industry as IMESAFR.  By establishing an acceptable level, the QRA tool may be used in a more consistent manner and risk measurements will be against a standard not themselves.

 

Analysis of Air Over Pressures Under a Negative Pressure Boundary

Harmonic energetic delamination of T2 building is being considered. The T2 building is within a containment structure that is under negative pressure to prevent radioactive material to leak out of the containment. A site specific blast design was proposed that made possible the delamination under negative pressure.

 

Analysis of the Influence of Emulsion Gassing Process

Application of Event Tree Analysis to Explosive Terrorism Risk

An Event Tree Analysis (ETA) that incorporated a review of existing lexicons and a series of meetings with stakeholders and subject matter experts was used to develop an event tree structure for assessing the risk of explosive terrorism to the US homeland.

 

Application of Fan Hole in Rock Bank Blasting in Docks

The VCR fan hole blasting techniques usually used in underground mining are used in this paper for rock bank blasting, which is not only improve the working environment, but also enhance efficiency and reduce cost. The rock bank can be effectively blasted using hole-by-hole initiation technique to reduce vibration.

 

Applying the Concept of Difficulty of Tunnelling to Brazilian Cases

Applying the concept of the difficulty of tunnelling by drilling and blasting (D&B) to selected cases from the Brazilian tunnelling industry. Tunnels in Brazil tend to be unrealistically more difficult to excavate when compared to similar excavations in similar geologies elsewhere in the world.
