    Mining ships are generally rather slow aligning and warping, and docking and undocking all take up time that could better be spent mining. Jetcanning is a decent method of solo mining, especially if the miner has at least one alt. With one character, the miner can fill two jetcans before warping back to a station to pick up a Miasmos.
