How do i find Ice Field Locations for ice mining??

I believe, don't take my word on this, that certain solar systems have them exclusively, and they're listed just like you would find normal asteroid belts.

See if this can help you out (found using a quick google search) http://eve-online.itemdrop.net/eve_db/universe/search/

[blank] [in region with name containing] The Forge(example, wherever you want to find them)

learn to use dotlan. http://evemaps.dotlan.net/

look at region, and the ones with a blue circle include an ice belt.
