Explosives is a Fallout 3 and Fallout: New Vegas skill, replacing the Traps and Throwing skills from previous games. It was also going to appear as a weapon skill in Fallout: Brotherhood of Steel 2, the equivalent of skills in other Fallout games. Its governing primary statistic is Perception.
Fallout 3
Example: A starting Perception of 5 and Luck of 5.
"The best way to solve a problem is to make it go away."
The Explosives skill governs the ability to use all mines, grenades and Explosives skill based weapons (excluding missiles and mini nukes - see Big Guns).
The higher your skill, the higher the damage you inflict. The Explosives skill also affects the distance and accuracy of a thrown bomb (e.g. frag grenade, pulse grenade etc.)
The player's Explosives skill determines how close you can get to a mine before it detects you, as well as how long the mine will take before it explodes. There does not appear to be a minimum Explosives skill necessary to disarm a mine, so long as you can run up and activate it fast enough.

Fallout: New Vegas
Example: A starting Perception of 5 and Luck of 5.
In Fallout: New Vegas, many more types of weapons fall into the Explosives category. Any weapon that was originally a big gun in Fallout 1, 2, or 3 and used explosion type ammunition (such as the Fat Man, or Rocket Launcher), was moved to this category when the Big Guns skill was removed.

Affected weapons
Note: most explosive weapons have damage listed as "1 (or 2) + some number." The 1 (or 2) is the damage that the projectile (like a thrown grenade) or placed explosive (like a mine) does upon a direct hit, pretty much just from physics. As such, that number can generally be ignored for most intents and purposes (and damage calculations for grenades and mines in the Pip-Boy 3000 appear to do so).

Notes
- Player placed mines are not triggered by the player himself, companions or NPCs of a faction the player character is currently disguised as.
- Explosives placed prior to temporary boosts wearing off will still retain the boosted damage bonus from the higher explosives skill when they were placed. In other words, a frag mine placed prior to a Patriot's Cookbook wearing off will inflict the same damage after those items have worn off.
- Though most explosive weapons have a "skill requirement", indicated by the number next to the explosive symbol in the Pip-Boy menus, the player can wield these weapons regardless of skill. The same is true of Guns, Energy Weapons, Unarmed weapons, and Melee weapons.
Fallout: Brotherhood of Steel 2

Explosives was going to appear as a weapon skill. It increases the base damage inflicted by explosive weapons.[1] Assuming Fallout: Brotherhood of Steel 2 would have used a points based system like its predecessor, it is able to be increased.
