The Explosive Mines take the form of black iron balls, both as an icon and on the tracks.
In gameplay, the Explosive Mine can only be obtained at random from Item Boxes by Omega, Knuckles, Metal Sonic, Sir Gawain, Wave, Zavok, and Zeena. As with most other Items, Metal Sonic can also use the Explosive Mine if he uses the Steal Item to steal it from the aforementioned user.
Once obtained, the player can utilize the Explosive Mine by pressing its icon on the bottom of the HUD. When used, the Explosive Mine will drop its iron balls some distance ahead of the user's current location on all the lanes that the user is not currently on. If a character, including the user themselves, touches one of these iron balls, they will explode and damage the character, causing them to lose Rings and slow down momentarily. To avoid the Explosive Mine, the playable character must either jump over its iron balls or run in-between them.
The Explosive Mine can also be upgraded by leveling the user up to level 4, 10 and 16 respectively. For each upgrade, the player will increase the damage dealt with the Explosive Mine.
