Blasting, as a historic footnote, started in Hungary within the yr 1627, and Konya is 100% Hungarian. However know-how has since improved these strategies considerably, he famous.
His nice grandfather was a mining and metallurgical engineer in Ohio, and his grandfather a mining engineer who based the Worldwide Society of Explosives Engineers.
“Since I used to be about two years previous I’ve been out on blasts at totally different mine websites and building initiatives,” Konya stated.
After rising up in Ohio, Konya labored and lived in Missouri, Louisiana and New Mexico, working with Cargill and Freeport McMoran. At Missouri College of Science and Know-how, Kona accomplished bachelor’s, grasp’s and PhD levels in mining engineering and was later an adjunct professor on the Colorado Faculty of Mines.
Konya has authored the net, on-demand Introduction to Blasting course at Edumine for 2 years, teaching on fashionable strategies which have changed previous ideas to allow blasters and engineers to make important enhancements to the drilling and blasting course of. Right here’s a glimpse of the syllabus:
Q: What can professionals count on from the Introduction to Blasting course?
Konya: Blasting is the center of the mining trade. With out it, there’s no approach that we might do what we do. I feel it’s the cornerstone of the complete trade. The best way that you just blast goes to find out all the things out of your slope stability to your crushing, your grinding, to all the things you do this determines your work segmentation. [Blasting] is step one, and with out it, we wouldn’t have mining anyplace close to the dimensions we do immediately.
Q: Who can profit most from the course?
Konya: Anybody transferring right into a mining function on the engineering or administration degree that has restricted expertise in drilling and blasting. You need to have blasting right- even when you’re not working within the blasting area, this course is ready in a approach that will get you in control sufficient which you could shortly and simply consider – is the blasting at mine web site appropriate?
Q: What has modified in blasting methods over the previous few years?
Konya: There have been lots of adjustments. During the last 5 years we’ve seen a big improve in the usage of digital detonators. From a blasting perspective, it has allowed us to actually hone in and design higher blasts with extra flexibility within the timing. They’ve additionally led to some safer manufacturing as a result of there may be further testing.
We’ve had some latest improvements within the precise explosives we’re utilizing, so the emulsions we’re utilizing are higher and final for longer intervals of time. They’re additionally extra highly effective.
The drilling know-how has additionally improved, and we’re seeing lots of new software program management methods, with drills outfitted with lots of further sensors, we’re capable of higher decide up the rock. New softwares are capable of pull that in, with drone imagery, put collectively utilizing synthetic intelligence, to [tell] what that rock is doing. We will have a look at previous blast outcomes and actually have the ability to inform what occurred..and decide how that [next] blast goes to perform.
Q: How does ESG issue into present blasting methods?
Konya: There was latest work completed on what’s referred to as ‘inexperienced explosives.’ It’s utilizing hydrogen peroxide to make emulsion explosives that eliminates all of the poisonous fumes from blasts and pulls nitrates out.
In these new inexperienced explosive initiatives, we’re taking a look at creating explosives that, underground or floor, are going to provide much less poisonous fumes. The top aim is to utterly remove poisonous fumes, not less than as a lot as is possible. It would eliminate lots of the large clouds above the blasts from the nitrogen oxide. Carbon monoxides are additionally vastly lowered.
One thing that we’ve been getting alot higher at in blasting is the social aspect- blasting is one thing that might probably derive some hazard to native communities – we’ve been utilizing totally different AI methods and softwares, monitoring how a lot explosive we’re placing down.
Q: What are some blasting misconceptions?
Konya: There’s all the time been a nasty view of blasting that if you’d like higher efficiency, it’s a must to spend more cash. The powder issue design stated – if you’d like higher fragmentation, much less floor vibration and any elements necessary, put extra explosive within the floor. It was an outstanding gross sales pitch, nevertheless it didn’t work.
As we speak, we perceive blasting higher, the engineering rules and the trendy methods and approaches. We will change how we design a blast to get higher efficiency, whereas really utilizing much less explosives.
