Our Range of Products
Since Ammonium Nitrate (AN) is a primary ingredient in our bulk and packaged explosives, we own and operate several strategically located plants where natural gas is converted into AN prills and solution. Our ability to manufacture and transport more than a million tons of AN per year is vitally important to ensure that a reliable supply is available for our manufacturing facilities, distributors and customers
Today, 95% of all explosives consumed are delivered in bulk. At large-scale mines and quarries, specially designed trucks combine the ingredients and pump or auger them into the borehole.
Bulk explosives range from simple ANFO (ammonium nitrate + fuel oil) to straight emulsions and include a wide variety of ANFO/emulsion blends, each with unique performance/cost characteristics.
ANFO, a mixture of ammonium nitrate prills and fuel oil is the most economical and commonly used explosive when boreholes are dry and the geology is suitable. For small shots, ANFO is premixed and packaged in 50-pound bags.
Our line of packaged emulsion explosives is typically produced in chub-type cartridges from one to three inches in diameter. However, paper wrapped emulsions and larger diameter shotbags are also commonly used. Packaged emulsions are widely used in quarry and construction work. They have excellent water resistance and do not contain nitroglycerin.
As the only remaining dynamite manufacturer in North America, we recognize that although emulsions have replaced dynamite in many applications. However, dynamite still has performance and reliability characteristics that make it a superior product for certain demanding blasting applications. Dynamite is also commonly used as a booster in an ANFO column.
Although non-electric detonators are now widely favored, many blasters still prefer electric detonators for the ability to test the circuit before firing the shot. Our electric detonators are manufactured in a range of precise millisecond and long-period delays. This allows the blastholes to detonate in a predetermined sequence to control ground vibration and improve rock fragmentation.
Non-electric detonators utilize a plastic tube to carry a signal to the detonator instead of a pair of wires. The inside wall of the tube is coated with a reactive powder. When ignited, the shockwave travels inside the tube at 7,000 feet per second to the detonator.
The major advantage of non-electric initiation is its immunity to potential misfires caused by radio-frequency energy or other stray electrical charges.
Instead of pyrotechnic delay elements, electronic detonators utilize microchips to deliver more precise timing to improve blasting results. Our DigiShot® electronic initiation system is an important advance in technology, enabling users to achieve accurate benefits of electronic initiation systems with the easy connections of traditional non-electric shock tube systems.
Nearly all of today’s bulk explosives (and some packaged explosives) are not detonator-sensitive. That is, a standard strength detonator fired in the explosive will not cause it to detonate. Boosters amplify the detonator’s energy to initiate a reliable full-order detonation in the explosive column. We manufacture a full line of cast boosters in a variety of types and sizes.
For blasts that require the exceptional strength and durability of a detonating cord in their initiation system, we manufacture a line of reliable, high quality cord in all of the popular core weights.
The gas and oil exploration industry utilizes specialized explosives to generate an acoustic wave for seismic data acquisition. We manufacture a comprehensive line of seismic explosives that are in use by exploration crews worldwide.
We pioneered most of the bulk explosives delivery equipment in use by the explosives industry today and we have always been the leader in introducing new and innovative explosive delivery systems.
