The STO wiki states that it affects all tranphasic projectile damage, including mines. The same will apply to all kinetic-damage boosters.

So yeah, use the Transphasic Compressor to boost your transphasic damage.

Also, be sure to use STO wiki as a resource. It's useful for older, established features of the game. It's not updated as regularly as it should be, so be wary. Try double-checking with other resources if in doubt.
