What is the recommended length of overlap when taping two lengths of detonating cord together?

• A. 2 inches (5cm)
• B. 4 inches (10cm)
• C. 6 inches (15cm)
• D. 8 inches (20cm)

Answer: (B)

The recommended length of overlap when taping two lengths of detonating cord together is 4 inches (10 cm). This measurement is specified to ensure a secure and reliable connection between the two sections of cord. Proper overlap is critical for maintaining the integrity of the explosive device and ensures a consistent and effective transfer of detonation signal between the cords. A 4-inch overlap strikes a balance between providing enough surface area for effective bonding while not being excessively long, which could create unnecessary bulk and complicate handling or application. This guideline is based on safety practices that consider the physical properties of the detonating cord and its functionality in controlled blasting operations. Following these standards helps minimize the risk of misfires or incomplete detonations, thereby enhancing overall safety in mining operations.
