All of Cybertrons mines are... Unique.

They are found on Cybertron and its moon used to mine for Energon and other metals... always using enslaved or low-caste robots by those in power who couldn't even handle a inch of rust on them. These mines housed new and basically ancient technologies for dangerous mining operations, even when automated mining systems have begun to take over.
