Mine Help

How do you get the second mine open!

Ummmmm, are you talking about DS?
If not, just wait until winter. You'll be able to walk across the frozen lake ice to the mine.

If you want to go there year-round, go to the bottom of the first mine, the one by the goddess pond, on or after your 3rd year and dig, you'll get a teleport stone.
