You can find a few guides here Resources for the New Citizen although I don’t remember there being any on the topic of Mining.
What sort of stuff would you like to know? Mining is somewhat straight forward.
Pick a ship appropriate to you needs and ability: Venture, Mining Barge, Exhumer, Industrial Command ship (Porpoise/Orca), or Capital Industrial Command Ship (Rorqual), go find a belt or anomaly to mine in and once your Ore Hold is full you unload in Station/Structure and rince and repeat.
