Dominion mines are a reward that can be purchased after killing 400 bosses and finishing all special challenges, with the exception of Sunfreet, within the Dominion Tower. Each mine costs 1000 coins. You can only place 2 Dominion mines per minute.

These mines always hit 20% of the monster's maximum life points, up to 10,000 melee damage. They are useful if you want to get a strong hit on monsters with high life points such as rune dragons. They cannot be used inside the tower itself, nor in the Sunken Pyramid.
Dominion mines can only be triggered by NPCs with less than level 138 combat, making most bosses immune to them. Gregorovic is an exception and will be damaged, likely due to his combat level changes randomly during the fight between 1 and 1000.
Monsters will not become aggressive when hit by a mine.
