Rock Blaster is a job that involves using explosives to break apart large rocks. The two most commonly used explosives for this job are AMP and TNT, which are abbreviations for ammonium nitrate and trinitrotoluene, respectively. Ammonium nitrate is an oxidizing agent that is used to create a chemical reaction that breaks apart the rock, while trinitrotoluene is a high explosive that is used to create a shock wave that breaks apart the rock. Both of these explosives are highly volatile and require special safety precautions when handling them.
