Why are you mining coal ever? Mining sucks so much.
currently my most efficient way to train smithing is steel platebodies (also very profitable). getting iron is as easy as running from the rimmington mine to the port sarim bank deposit. the coal is problematic since I can't go to the dwarven mine as my combat lvl isnt high enough yet to not aggro king scorpions, so I have to go to the always crowded barbarian village. and on top of that mining is SUPER slow even with rune pick.
though i'm discovering new stuff in the game all the time so I wouldn't be surprised if there was a better way to go about this.
