No adv. mines are necessary for one steel mill, when you raid Iron and/or Coal. One raid on a mine are 30 of this res. With 2 coal mines and 2 raids/day you have 1500 coal/day. With 6 iron mines (you could have 7, but it seems hard to get all) you have 4320 of 4500 (need 6 raids) I think, that iron-raids are very easy, cause every friend have 5-7 iron mines too (on higher lvl)
