NEI is your friend, but make sure you can craft a drill first, cause it is required, a scanner, mining pipes.
Mine is just sitting around taking space, until I can craft a drill.
Wait, the advanced miner needs a drill since when? 0_o
Do you mean the normal miner? The advanced miner is a pretty recent addition to the experimental builds. It only really requires a scanner to work, but unlike the miner it's made from pretty expensive machinery(a teleporter and an MFE amongst them). When given a redstone signal it scans a large square below it (the size depends on whether you use an OD or OV scanner) block by block all the way down to bedrock, much like the buildcraft quarry sans huge construct, and digs any eligible blocks. I say eligible blocks because unlike the quarry it has a whitelist/blacklist functionality built in. So, if you blacklist dirst, stone, gravel and maybe the granites, it can dig an area of resources without defacing it. It'll also mostly waste small amounts of energy for each block scanned while keeping the larger energy consumption for actually digging blocks relatively low if used that way. Lastly, overclockers seem to speed it up without increasing the energy cosumed per block, though I could be horribly wrong on this point.
