Mining Final Pit Walls and Road Cuts

Alan Dolan, Boliden Tara Mines

Alan discusses precision blasting, pre-split drilling and blasting close-to-finish walls. He also discusses two open pit mines with some information from a road extension.

Enjoy the Ride

Brad Brown, Dyno Nobel

From the early days of technology in the explosives industry - teaching users to run high speed cameras and handing out laptops - to using some of the most advanced tools, the explosives engineer has had to adapt. A few simple truths remain, though, and the aspiring engineer needs to enjoy the ride.

Blasting Can be Fun!

Paul Sterk, Austin Powder

As the Homestake Mine came to a close in the early 2000s, a decision was made to blast the remaining explosives in the mine rather than send them back to the surface. This is a story about one of those blasts.

Hour 2: Environmental

Blasting to Protect and Distribute Water Resources

Jerry Wallace, Wallace Technical Blasting, Inc.

Jerry discusses blasting at two dams and at two wells: One dam served as water reservoir for City of Denver. The other was storage for court-order, commerce-water for downriver states. Two wells were being decommissioned and plugged to protect groundwater from surface pollutants.

Blasting to Improve Fish Habitat

Kristen Kolden, Alaska Seismic

Kristen will describe how blasting projects are designed to minimize and mitigate impacts to fish, wildlife and their habitats. She will discuss projects that use explosives to enhance natural habitats.

Dam Beavers

Kyle Perry, Missouri S&T

Beavers were threatening the integrity of a levy of a several acre pond which was uphill of a residence. The pond spillway pipe was constantly being plugged by beavers leading to rising pond waters which were starting to overflow. Upon the beavers being removed from the pond, their den was destroyed to discourage a return.
