How many detonators are recommended to be used together to initiate detonating cord in critical blasts?

• A. One
• B. Two high strength
• C. Three
• D. Four

Answer: (B)

The recommendation to use two high-strength detonators to initiate detonating cord in critical blasts is based on safety and reliability in explosive handling. Using two high-strength detonators provides redundancy, ensuring that if one detonator were to fail, the other would still successfully initiate the blast. This dual detonator system helps to minimize the risks associated with misfires and enhances the overall effectiveness of the initiation process.

In critical blasting scenarios, the stakes are typically higher, such as in deep mining or sensitive environments, where precise and reliable detonation is crucial. The use of high-strength detonators specifically is important due to their enhanced performance and ability to transmit the initiating signal more effectively to the detonating cord. This practice aligns with established safety protocols in the mining industry, enhancing both operational safety and efficiency during critical blasting operations.
