Frequently Asked Questions The World of Explosives

In blasting, the unit of measurement we use to describe this motion is peak particle velocity. The Richter Scale reports the power of an earthquake or its magnitude. It’s an estimation of the energy released at the source. In blasting, it would equate roughly to the total weight of explosives used in a blast.

Utilizing bulk emulsions in quarry blasting Pit & Quarry

Jun 13, 2019 Blast design should be a balancing act of getting the best fragmentation without creating unwanted impacts such as excessive vibration, airblast, flyrock or NOx. Using bulk emulsions as part of the blast design process is a smart way of managing these impacts. Plan for known or suspected wet areas by drilling patterns for higher density products.
