This is a list of unnamed miners who worked on the Orpheus Mining Colony on Luna in 2155.
Alien miners
These two alien miners were working for John Frederick Paxton at the Orpheus Mining colony on Luna. (ENT: "Demons")
Paxton was the leader of the anti-alien movement Terra Prime which was headquartered in the colony. So it is odd that an alien would be working at his facility. It could be that Paxton had a small number of aliens employed in order to divert suspicion of his illegal activities.
Human miners
These Human miners were working at the Orpheus Mining colony for John Frederick Paxton. They were probably members of the anti-alien movement Terra Prime which was headquartered in the colony and participated in the capture of Trip Tucker and T'Pol. (ENT: "Demons", "Terra Prime")
All miners were played by background actors, some in cameo roles, who received no credit for their appearance.
