Pictures? I too havent seen a good description of how to set this stuff up.
(Sorry I know it is a little complicated but it is the only picture I have on hand.)
Below is an advanced setup that I tested on a TMI world, please ignore the nuclear bomb testing hole at the top part of the screen. There are 4 miners here, each one has 2 pumps right next to it, each machine has a chest next to it, in the middle there is one geothermal generator to power all of them. (One can't really power all of them but that is fine for that test. In the next test I added more geothermal generators to keep the mines and pumps going 100% of the time.) Below the pit is an infinite lava source using a nuclear reactor exploit, this part is optional. Inside of all the pumps make sure you have put in empty cells. Inside the miners make sure you use just a normal drill, DO NOT USE A DIAMOND DRILL. (There is a bug and they mine to fast for the pumps to keep up with so the miner will then stop after drilling only once because there is no place to put the lava that it would mine next because the pumps aren't ready.) Then add pipes and your scanner to the miner. You can cut this down and just use one section of Pump-Miner-Pump and power all three by a geothermal generator. Though if you place a geothermal generator next to a pump along with a chest it should supply the generator with lava cells and then overflow into the chest.
