You have MFR, so you could use laser drills. A few of those coupled with a Fortune 3 pick will give you endless diamonds.
You could also run an MFFS quarry (cube forcefield with "disintegrator" and "collector" modules), which can dig stuff up quite insanely fast if appropriately powered.
There are a few other options, but appropriately-powered, laser drills are my favourite for "insane resource generation". I set mine up thusly;
All Fortune-able ores were routed to a chest next to an MFFS forcefield projector with a Field Stabilizer Module. This projected the blocks, one at a time, in front of a Tool Dynamism Tablet from Thaumic Tinkerer, over an AE transition plane; I also had two backup wooden golems in the area to gather anything that smashed beyond the plane (and put it in chests equipped with an export bus).
All told, with three laser drills running (and three picks working constantly) I could barely keep up with the flow of materials.
