We have the ability to dig holes that are miles and miles deep, not only that we have many abandoned mines which are empty and pose no threat to any water table. throw the waste down there and fill it up with concrete and dirt.

Sure that would work. But the problem exists that this radwaste has a half-life of hundreds of thousands of years. There has never been a civilization that lasted that long and the whereabouts of dangerous waste is likely to be forgotten.
It makes more sense to place the radwaste somewhere man is not going to have access in the next half-million years. Do you savvy?
