I never, ever use my space miner, ever.
I find the technology is too expensive, and not helpful enough i have the most fun playing all-factories, i like having a lot of ships, so I build bundles of +Economy Starbases to boost output.
(1) Do People agree with this assessment of the space mines and their miner? Am I ignorant in a slight way, I have faith you will tell me if I do.
So, knowing this, and the fact that it's a Cargo Hull I sat and thought what I could do with it that would be helpful (I used to scout). Then I saw Colony Ships also have cagor hulls so I started up grading the Miners into Colonies, it costs like 170.
I've found that, because I do this I can have another Colony up and running by the time my eco. hits the shitter, and this really helps on those perfect game where you rushed your colony ship out to a class 15, only to have a class 20+ be discovered by the vision gained by the colony.
I also Find the second turn (T1 spent upgrading) colony keeps my homeworld at 100% approval for an extra turn.
Note: I do this opening almost exclusivly, even on Tiny/Small Galaxy, and a bunch of Rares (rare plants, asteroids, ect.) And with this I use the second colony ship to farry people from homeworld to nat. expo. (natural expantion for the non-Starcrafters) On some maps I can do this an Infinite amount of times because moving one space into the plantet doesn't use a move
(2) Is this garanteed? part of a commonly used strat?
(3) Could I use the Miner better than as a colony ship
