speed of excavating stone?

[flamewolf393]

How fast can hard stone be excavated (not mined or processed, just removed) . I have 4 level 4 npc dwarven miners (max ranks in appropriate skills, but no shenanigans/OP combos) with 35 adult slaves, though the slaves are only cooperating out of fear and are not yet broken.

They also have 7 draft horses and 6 carts for hauling the stone.

The rules for this are actually in Races of Dragon, because Kobolds.

Its a profession miner check, varying based on what kind of rock you are digging through.
