In the bottom of the map were is suppose to be filled with lava, ash blocks and hellstone, there is no place for mobs to spawn. So when you do shafts here (horizontal ones, the vertical ones won't be a problem) to get to the hellstone, use stone blocks or other material to fill the empty space so that you couldn't fit in there, this way you make sure mobs won't spawn.

So you can have a real peace in there mining for hellstone, mobs won't disturb you.
