When connecting a Nonel detonator to B-Line, what must be ensured?

• A. The B-Line is at a higher elevation
• B. The tubing runs straight to the hole/collar
• C. All tubing is bundled together
• D. The tubing can cross over each other

Answer: (B)

When connecting a Nonel detonator to B-Line, it is essential to ensure that the tubing runs straight to the hole or collar because this minimizes the risk of kinks, bends, or snags that could impact the functionality of the detonation system. A direct and unobstructed path allows for a more reliable transfer of the signal from the detonator to the explosive charge.

Stray signals or delays in detonation can be caused by improper routing or physical interference, which highlights the importance of maintaining the integrity of the tubing's pathway. Therefore, having a straight run ensures optimal performance and safety in the initiation process, which is critical in a mining environment. In contrast, other considerations like elevation, bundling of tubing, or crossings may not necessarily provide the same level of assurance regarding safe and effective detonation initiation, thereby making them less critical in this context.
