Have I just awoken from a coma and travelled back in time to the EVE before ore mining ships? Like the venture? Or… The venture? Or even an endurance. Or mining barge, or porpoise. Why would anybody with a brain use a battleship to mine? Only reason I can think of is that Op lives in uedama and has a queue of people waiting for him to undock.
New players - use the venture. A good mining ship that you can get for free and fit cheaply.
