What differentiates the Nonel system from the Cordline system?

• A. Nonel can be used with any explosives
• B. Cordline can only be used with insensitive explosives
• C. Nonel is low strength while Cordline is high strength
• D. Cordline is safe for sensitive explosives

Answer: (B)

The distinction between the Nonel system and the Cordline system primarily revolves around their compatibility with certain types of explosives. The Cordline system is designed specifically to work with insensitive explosives. This means it is engineered to ensure safe and effective detonation without risks associated with high sensitivity explosives, which could potentially lead to unintended detonations.

This focus on compatibility with insensitive explosives makes the Cordline system particularly advantageous in mining operations where safety is crucial. By using insensitive explosives, which are less likely to detonate under unintended conditions, the risk of accidents is significantly reduced.

The choice reflecting that Cordline can only be used with insensitive explosives accurately captures its intended use, thereby highlighting its safety features designed for specific explosive characteristics. In contrast, other options do not accurately describe the fundamental differences between the two systems. For instance, stating that Nonel can be used with any explosives or that it is low strength compared to Cordline does not define the operational parameters effectively as the correct answer does.
