Which type of detonator is recommended to initiate detonating cord?

• A. Low strength detonator
• B. Medium strength detonator
• C. High Strength detonator
• D. Sensitive detonator

Answer: (C)

A high-strength detonator is recommended to initiate detonating cord because it is designed to provide a reliable and powerful initiation of the explosive. Detonating cord, often used in blasting operations, requires a detonator that can effectively transmit the shock wave necessary to ensure a uniform and instantaneous detonation along its length.

High-strength detonators achieve this due to their ability to produce a strong enough shock wave, which is crucial for properly initiating the detonating cord. This ensures that the explosive reaction propagates reliably, minimizing the risk of misfires and enhancing overall safety during blasting operations.

Other types of detonators, such as low-strength or medium-strength detonators, might not generate the necessary energy to adequately initiate the detonating cord, potentially leading to incomplete detonation or delay in the explosive event. Sensitive detonators, while potentially effective in some contexts, may introduce concerns about safety and handling due to their increased tendency to detonate from shock or heat. Therefore, using a high-strength detonator is the preferred choice to ensure proper initiation and maintain safety in mining operations.
