Final answer:
Priming a TNT block with Detonation Cord involves attaching the cord to an explosive booster that is inserted into the TNT. The cord transmits a pressure wave from an initiator, detonating the booster and the TNT. This is used in military, industrial, and mining applications.
Step-by-step explanation:
To prime a block of TNT using Detonation Cord, you need to understand that TNT (trinitrotoluene) is an explosive material that requires a high-velocity initiator or an effective concussion to properly detonate. Owing to its chemical stability, it is less sensitive to shock and friction, thereby presenting a reduced risk of accidental detonation compared to other explosives. TNT melts at a temperature of 80 ℃ (176 ℉), which is significantly lower than the temperature at which it spontaneously detonates, allowing it to be manipulated and combined with other explosives with relative safety.
When priming TNT with detonation cord, the detonation cord should be securely attached to the explosive booster. The booster is then inserted into the block of TNT. The detonation cord acts as a transmission medium for the pressure wave generated by the initiator, and upon receiving this pressure wave, the booster detonates, causing the TNT to explode. This sequence of actions ensures a controlled and efficient detonation of the TNT block. Such an operation would typically be performed in military, industrial, or mining applications where precise explosive results are necessary.
Moreover, since TNT neither absorbs nor dissolves in water, it can also be used in wet conditions without loss of efficacy. It has historically served as a standard reference for an explosive's sensitivity, and although this reference has now shifted to RDX, TNT remains a prevalent choice in various sectors, including the oil and gas industry where it is used in combination with hydraulic fracturing techniques.
