The Mining Process – Waihi Gold

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Getting Started (Thermal Expansion 3) - Feed The Beast Wiki

The theory here is that your ore processing plant really isn't going to be running of the time, and probably not even 50% of the time. So if your ore processing plant is running, say, 50% of the time, and it requires 80 RF to run at peak, then one Dynamo at 40 RF should be plenty to keep it running smoothly, assuming you have a sufficient reserve in your Energy Cube.
