Austin Powder Launches E*STAR Tunnel
Economical, Easy to Use, and Environmentally Responsible
July 2022. Cleveland, Ohio. Austin Powder, a leader in the manufacture, distribution, and application of industrial explosives and engineered blasting solutions, announces the release of its new E*STAR Tunnel, developed for rapid tunnel blasting deployment while reducing post-blast plastic residue in the muck pile.
Austin Powder is committed to continuously improving its products and is proud to introduce the E*STAR Tunnel detonator as the latest edition to the E*STAR Electronic Initiation System.
The robust design and exceptional leakage tolerance make the E*STAR Tunnel detonator and the accompanying blasting system reliable in demanding and extreme tunnel conditions.
The newly designed E*STAR Tunnel connector introduces less plastic to the blast site, while the neon colors allow for quick detection, even in a low-light underground environment. "Two of the great features of the E*STAR Tunnel are the economy of the product and the reduction of environmental impact on our customers." Says Campbell Robertson, Global Manager, Electronic Initiation Systems. "Even though the connector and the leg-wire were each designed to have less plastic, it is extremely robust and has proven to be an excellent product."
E*STAR Tunnel offers delays of up to 20 seconds, allowing customers to optimize timing to solve issues caused by excessive vibration or sub-optimal fragmentation. Using the flexible E*STAR Tunnel timing in the blast, along with accurately timed contour holes, can prevent overbreak, which improves wall stability with more advance per blast. This results in multiple production and safety efficiencies which makes significant positive impacts on every part of the operation.
The accuracy of the E*STAR Tunnel timing reduces scaling times and optimizes energy with significantly less over-break, which positively impacts the bolting and concrete spraying cycles.
With RFID capability and Sections & Intervals, the new Austin Powder programming method is specifically designed for tunneling. Programming and connecting E*STAR Tunnel detonators is a rapid process resulting in faster hole-loading and improved fragmentation with less oversized material. Campbell Robertson explains why. He says, "Unlike typical pre-set pyrotechnic delay periods, any detonator can go to any hole, and you assign your delays based on the sections and intervals you have preassigned on your Logger."
In a recent trial in Europe, customer Jiří Horčička, Project Manager, Metrostav Norge AS, said, "The E*STAR Tunnel system is very intuitive, so it is easy to handle for our blasters. The second advantage is that it has a very low environmental impact, and we as customers will definitely use this system in the future with no doubts."
Join Austin Powder on our mission to improve the world we live in through the safe and responsible use of explosives.
Austin Powder continues to develop technology to improve the efficiency of blasting processes. The E*STAR Tunnel technology is now available. Contact your local Austin Powder representative for more information.
