As alluded to above, a pair of tesseracts is great, it elimates the need for you to carry loads of fuel to a faraway dig site.
To explain further, at your quarry site all you need is the quarry itself and a tesseract. Plonk the tess on top of the quarry and set it to receive power/send items. Put it on the same channel as a second tesseract at your base, set this second one to send power and receive items.
Then feed whatever RF power supply you're making (as papa mentioned above, lava and magmatic dynamos are a pretty simple and effective solution) into one side of the tesseract, put down a chest next another side of the tesseract and you're done
If you've done it right, you're feeding power the the remote quarry, the quarry will then output items direct into the remote tesseract and these should just get dropped into the chest ready for you to collect.
