Which term describes desensitization of a charge by shock from an adjacent borehole?

• A. Desensitization of a charge by shock from an adjacent borehole
• B. Deflagration
• C. Propagation
• D. Shutdown/Cutoffs

Answer: (A)

The main idea here is how charges in nearby boreholes influence each other through the shock waves they generate. When one borehole detonates, its shock wave propagates through the rock and can reach a neighboring charge. That incoming shock can alter the sensitivity of that adjacent charge, making it harder to initiate or otherwise changing its response. This effect is described as desensitization of a charge by shock from an adjacent borehole. This term fits best because it names the specific interaction between a charge and the shock from a neighboring borehole—the desensitization caused by that external shock. Other terms describe different phenomena: deflagration is a slower, flame-like propagation rather than a detonation reaction; propagation refers to the movement of the detonation front itself; shutdown or cutoffs describe stopping a blast sequence.
