Trinitrotoluene, TNT, or more specifically, 2,4,6-trinitrotoluene, is a chemical compound with the formula C6H2(NO2)3CH3.
This yellow-colored solid is best known as a useful explosive material with convenient handling properties.
The explosive yield of TNT is considered to be the standard measure of strength of bombs and other explosives.

The junction of the face and the floor. Also, unbroken rock remaining at the junction of the face and floor.

A top fire percussion detonator is designed to function without any electrical connection.

Fires from the top of the gun.

Owen Oil Tools’ Resistorized Bridge Detonators are designed to detonate when an electrical current greater than 0.2 amps is applied. The 008 Top Fire Detonator is a resistorized electrical detonator manufactured to API RP-67 recommendations and employs a 51 Ohm resistor in the firing circuit. It is designed to be used in hollow steel carrier or scalloped gun systems in a top-fire application where the detonator has a directional output designed to initiate a bi-directional booster.

Tramp Material (Also known as Foreign Bodies) not intended to be present in a process (such as bolts, nuts, gravel, etc), that can have an adverse effect on the process and may cause an undesired event or deviation from the design intent.
