If you really want to fit a miner1 or miner2 to a mammoth or iteron 4 or 5, then go right ahead. Mammoths (by the time you can fly them) have a skill bonus to give you more than 6k m3, and with 4 tech1 expanders, you have 13k m3.
Miner1s will give you 40 m3 per minute, so it would take 327 minutes, or 5.5hrs, to fill the mammoth. Miner2s will give you 60 m3 per minute, so it would take 218 minutes, or 4.6 hrs to fill it. And you'll only be able to mine veldspar or scordite.
Just for a note, with a retriever and 2 strip miners, I can do that much in half an hour. Plus I can go into lower securities and be protected by my drones, so I can safely mine in 0.5 and access kernite and pyroxeres.
