Desensitization of a charge by shock from an adjacent borehole is described by which term?

• A. Desensitization
• B. Deflagration
• C. Propagation
• D. Shutdown/Cutoffs

Answer: (A)

Desensitization is the effect being described. When a charge is subjected to the shock from an adjacent borehole, its sensitivity can temporarily decrease, making it less likely to detonate. This is the phenomenon of desensitization, where external shock reduces the likelihood of initiation for neighboring charges. Deflagration would involve a slower, non-detonation burning process, which isn’t about sensitivity changes from a nearby blast. Propagation refers to the detonation wave moving through or between charges, not the reduction in sensitivity due to an adjacent shock. Shutdown or cutoffs describe deliberately stopping or halting a detonation, not the temporary desensitization caused by a neighboring blast.
