"Blast" or shot is?

• A. The act of detonating explosive materials joined by a shared initiation system and a single firing device
• B. A test blast
• C. A ventilation method
• D. A water jet

Answer: (A)

A blast is the detonation of explosives that have been placed in multiple holes and tied to a single firing device through a common initiation system. When the firing device is triggered, all the charges go off as one event (or in a controlled sequence), creating rock breakage from that single detonation. This definition captures what the term “blast” or “shot” means in blasting practice—the actual detonation act triggered by one initiation system—rather than referring to a test or separate processes. A test blast is a specific kind of blast used to evaluate design or rock properties, but the fundamental concept described is the single, coordinated detonation event. It isn’t a ventilation method or a water jet, which are unrelated to the blasting detonation itself.
