What is the minimum distance required between flammable explosives and detonators for storage in an underground mine?

• A. 5 meters
• B. 8 meters
• C. 10 meters
• D. 15 meters

Answer: (B)

The correct answer is based on safety regulations regarding the storage of flammable explosives and detonators in an underground mine. A distance of 8 meters is specified as the minimum separation to prevent a potential explosion from igniting the detonators. This distance is crucial as detonators are sensitive devices that can initiate the detonation of explosives, and in the event of an accidental ignition or explosion, a larger distance helps mitigate the risk of a catastrophic chain reaction.

In addition to safety culture, this regulation is grounded in the understanding of blast dynamics; the further away the detonators are stored from the main explosives, the lower the likelihood of explosive reactions occurring due to detonation shock waves or heat. This safety measure ensures that even in a scenario where an explosion occurs, the risk to personnel and infrastructure is minimized by maintaining a safe operational distance.

Understanding the rationale behind this guideline helps reinforce the importance of adhering to storage protocols, ultimately contributing to a safer working environment in mining operations.
