There are two ways to create a mineable region on your map.

Step 1 :
Creating a cave entrance using tiles 01D3 to 01DB

Now you have the two options :

1) using static items
place static-items "into" the mountain or directly on your gameserver and make it static. This has the effect, that you don't use up space in the dungeon-region

2) mapping the cave and using map-teleporters to link it to the entrance
This is my favorite way.

I use normal mountain-tiles to simulate a "cave-wall", then i fill up the the inner part with Dirt-Tiles and (using transitions dirt->cave floor) the desired cave floor.

At the end it looks similar to this (of course using other textures and making the "floor" more even.
