Building on the success of the Nxburst Safety Cartridges, Coogar Sales and Services is bringing Nxco’s FRAGMENTOR to North America through its extensive dealer network. This self-stemming cartridge builds on the ease of use and efficient rock breaking capabilities that the Nxburst Safety Cartridges have provided users for years.
The FRAGMENTOR has incorporated a retaining device that will hold the self-contained cartridge within the blast hole. This allows for ease of use in both horizontal and overhead use, ideal for work in underground mining.
By using axial-piston technology the cartridge seals itself in place upon initiation to provide a perfect guaranteed seal, ensuring the effectiveness of the propellant technology.
The FRAGMENTOR is available in a 43-mm diameter with gram weights of 80, 120, 180 and 240 enabling the user is given the ability to optimize their blast pattern.
The long sought-after dream of continuous mining is now attainable with the FRAGMENTOR and its lack of noxious gases. Using an industry standard 45-mm (1 ¾-in.) hole, the gas produced during deflagration mainly consists of nitrogen and carbon dioxide.
Dust is also kept to a minimum as the technology breaks rock under tension rather than compression always using the optimal amount of force required. Air blast is also not created as the rate of burning is approximately 350 m/s, with no shockwaves present during a blast allowing personnel to remain down in the mine during the operation and re-entry into the blast area within minutes.
The time savings of the “load and go” abilities with the lack of required stemming make this product ideal for underground mining applications where stemming can always be an issue.
The FRAGMENTOR is perfectly suited to secondary breakage, civil excavation, concrete demolition, mass rock excavation and underwater blasting. The high heaving effect produced by the FRAGMENTOR cartridge guarantees performance reduces the grams/m3 of propellant required and with an ability to increase the burden, reduces the cost of rock fragmentation.
