AI Technical Summary
Existing starter detonators in blasting systems require reliable infrastructure with harness wires and communication networks, which are prone to issues like wire cut-off and electrical leakage, especially in high-risk areas, and replacing pyrotechnic delay detonators with electronic detonators is costly.
A wireless starter detonator assembly with a through-the-earth wireless receiver and electronic detonator, connected via a flexible conductor, initiates pyrotechnic detonators using a wireless fire signal, eliminating the need for physical connections and allowing remote firing from a safe distance.
Enhances safety and reduces infrastructure costs by enabling remote initiation of detonators without physical connections, allowing reuse of the receiver and reducing risks associated with wired installations.
