I created a new mod that enhances the underground a bit. It also makes mining slightly harder.
This mod now includes 62 underground biomes.
Some of the new blocks:

List of features:
Currently, ores are a huge waste of HDD. The vast majority of ores will be never mined out so there is no need to store the information about them. It's more effective to fill the bulk rocks by a single node and generate the ores when the stone gets exposed to the air. This tricks makes the world compress better. Believe or not, the world size will be like 3 times smaller using this feature. It's not glitch-free though. Before you use this, you need to remove the definitions of all ores which generate in default:stone from other mods manually.

If you have some ideas of more underground biomes, I might add them in a future release.
