Quarries work fine when set up properly. You can use combustion engines if you're lacking caution, but using geothermal or solar, or the like works better. All you need to do is connect you power source through one of the electric engines (depending on how fast you want your quarry) then connect it to the quarry with conductive pipes. Works great.
