Austin Powder announced the E*STAR Tunnel for rapid tunnel blasting with reduced post-blast plastic in the muck pile. The detonator features a robust design with exceptional leakage tolerance, the company said. The blasting system is made of comparatively less plastic, and has neon colors for quick detonation in low-light environments.

E*STAR Tunnel offers delays up to 20 seconds. The accuracy of the timing reduces scaling times and optimizes energy, with significantly less over-break, Austin Powder said. “Programming and connecting E*STAR Tunnel detonators is a rapid process resulting in faster hole-loading and improved fragmentation,” it said.
