Your fort is on layer 1 (more than likely).
Caves and most mines are on Layer 2.
If you build a mine hole inside a cave or mine, it takes you to layer 3.
Build another one there, and it takes you to layer 4...
Sadly the strength requirements for mining deeper are much much higher every layer. On layer 2 I can blast through rock in a few swings. On layer 3, it's Much Too Hard. Get that tobacco, beer, and boar tusk snuff stacked atop your bear cape and bear tooth talisman, and you can mine out some ore for a few seconds. True mining is done in drunken, violent spasms a few seconds long each.
