iRing Inc has introduced what it says is an extensive, searchable, comprehensive Knowledge Base that provides answers to questions concerning the use of commercial explosives in mining and construction applications including the physics of the detonation reaction and how this is used in mining for fragmentation.

The iRing Knowledge Base provides in-depth analysis and descriptions of the use of commercial explosives under many topics including types of explosive products, priming, temperature, and pressure effects along with applications and use of explosives in mining and construction. The material has been collected over years of experience in explosive manufacturing and mining by Christopher Preston, Consulting Engineer and VP Research and Development for iRing.

The knowledge concerning the use of explosives as well as case histories and other notes are taken from a broad range of sources including authors skilled in the art as well as personal experience, according to iRing. These works are acknowledged where appropriate and are presented to provide answers to the world use of explosives in mining and construction for everyone.

“Many times, it is just handy to have a place to look up information without doing a rigorous search,” iRing says. “Hopefully, some of the information provided here will be useful. We have tried to acknowledge content that came from outside our realm of experience and we have acknowledged those authors who have provided input in the explosives technology public domain who are used as credible references.”

The Knowledge Base provided by iRing Inc is an extensive collection of information covering the years 1971 to the present. Over that period, commercial explosive products have changed drastically moving from dynamites and canned explosives such as Ammonal and Nitramon to ANFO, water gels and emulsions.

“Much work was completed by Dupont De Nemours and other large commercial manufacturers introducing the water-gel and emulsion families into a stream of safer commercial explosives,” the company said. “These could be used in a host of mining operations – from surface blasting, open-cast mining, and quarrying as well as construction to underground mining operations. Next followed dynamite’s replacement – emulsion explosives, which can be produced in both small and large diameters of charge for large mining operations and construction. Large quantities of bulk explosives can be delivered to the blasthole using pump or auger trucks with loading rates of hundreds of kilograms per minute.

“Delivery records are not only maintained on the trucks but also in the cloud for strategic data handling to arrive at the lowest cost of production. Extensive use of electronics in mining has affected production levels and, in particular, safety. Mine communications have improved to such an extent that normal operational activities can be handled by iPhones and/or tablets for production reports and foreman’s logs.”

iRing concluded: “Perhaps one of the best technologies introduced during the initial years of this century was the production of electronic blasting detonators giving timing accuracies that allow precision blasting methodologies surpassing traditional practices when blasting close to damageable structures.”
