What type of connection is required to effectively use Nonel assemblies?

• A. Cement bonding
• B. Tape wrapping
• C. Trunkline connection
• D. Welded joints

Answer: (C)

For the effective use of Nonel assemblies, a trunkline connection is essential. Nonel assemblies are often employed in the context of blasting operations, where they serve as a means to initiate explosives safely and efficiently. The trunkline facilitates a reliable and continuous connection between the detonation source (like a detonator) and the blasting agent.

Using a trunkline ensures that the transmission of signals or the initiation of explosives occurs without interruption or interference, allowing for coordinated blasting operations. This is particularly important in mining, where the timing and sequence of blasts can significantly impact safety and operational effectiveness.

The other options, such as cement bonding, tape wrapping, and welded joints, do not provide the necessary characteristics for safe and reliable communication or connection needed for Nonel systems. While they may serve purposes in different contexts or applications, they lack the specific attributes that make trunkline connections ideal for the requirements of Nonel assemblies in blasting scenarios.
