Looking for an adventure covering a lost/abandoned/ruined mine

I'm looking for an OSR (OSE compatible) adventure that is about some old ruined mine. The story for my campaign for this mine is 300 years ago this was a prosperous mine but the Cataclysm came and most of the area (including the mine) was swallowed up by the earth (yes, the same Cataclysm in Dragonlance).

Does not matter what the theme of the mine is, the party will get word of a possible location for this long forgotten mine, they go to investigate and yes they find it.

Any suggestions?
