There's a map somewhere of what can be mined safely from the position of the support. The tile doesn't have to be covered completely.

Only full coverage counts, me thinks.
Center of the tile has to be in the radius
I supposed I'd have to work out the math, but could a square be 70% covered by the support and not have the center inside the arc? I mean, not with an arc of a perfect circle, at least. If it were an elliptical or parabolic curve of some sort, it would be possible.
That said, visuals can be misleading when projected. Better safe than sorry unless you're good with counting out tiles away from the nearest support.
