Electronic Detonator Precision Allows Multiple Priming to Improve Fragmentation
Document type: EEG Guide
Categories: Explosive Engineers Guide, Asia Pacific

To test the ability of the DigiShot® initiation system to deliver firing times insuring independent detonation of the primary explosive at both ends of the column, a production blast was designed to test two techniques of initiation and determine the best method to use for fragmentation. One improved half of the blast was designed for both top and bottom primers to detonate simultaneously. The other half of the blast was programmed with a 25ms delay between the bottom and top priming unit firing times.

Observations of the blasted material after detonation showed a definite difference in overall fragmentation and oversize. The side of the blast with primers programmed to fire at the same time showed better fragmentation and reduced oversize. Mucking of the blasted material confirmed the initial observations made at the time of the blast event.

As part of a continuous improvement process, DIFFERENTIAL ENERGY has been introduced in the Truck/Shovel areas of the pit for trials. Multiple areas have been tested utilizing different densities on the top and bottom of the hole. The holes were then loaded with the same amount of explosives, or less, but due to the lower densities the explosives column height has been increased to improve energy distribution in the blast hole.

DYNO 42™ USED FOR VIBRATION CONTROL
 BACKGROUND
PRIMARY MINE CONCERNS ADDRESSED BY
DYNOCONSULT®
In the process of converting to electronic detonator
business at a large, Western coal operation, the mine had
implemented timing sequences for cast shots based on
material throw. However, primary concern at the mine
is vibration control at nearby gas wells and electrical
substations, as well as vibration induced highwall damage
that could pose safety issues to mine employees working
below the highwall.

There was a need to prove that the Dyno Nobel/JV
approach provides needed vibration benefits.

A side by side test was arranged by the JV to determine
the feasibility of the competitor approach.

A significant number of patterns were loaded and shot over several months after the new trucks arrived. The shots looked very good from the surface, but as time went on complaints started coming from some of the shovel operators working in certain areas of the pit about hard digging in the toe area of the shots. Based on this feedback, it was determined that DIFFERENTIAL ENERGY might provide a better solution to solve the toe issues that had been reported and observed in about 30% of the shots.
