Do you mean extinct volcanoes? Because we would be digging into magma if we started working on the dormant ones.

Volcanoes aren't hollow tubes with magma at the bottom. They either have a plug of solidified lava above the magma chamber, or are actively releasing magma upwards. Either way, you would still have to dig through rock and magma.

So out of volcanoes comes lava and lava pretty much destroys everything we have to touch it with. I know you said dormant, digging deep enough gets you to a bunch of lava which is the limiting factor.
