How do you disable quarries?

How would you go about disabling only quarries, but not the Buildcraft mod itself.

I have tried adding the fakeplayer [buildcraft] to a group with no building permissions, but this conflicted with Towny and caused the server to crash.

Hmm, so no ideas?

Add the quarry item to the disallowed-items section of Commandbook's config.yml.

The server already has around a hundred quarries placed. This would only prevent more to be placed.

How do I stop these existing ones, or remove these existing ones from the game?

I'm not sure, but I think MCEdit can replace all the blocks with air or something. Then again, I've never used it nor do I know if it works with tekkit or not.

Give it a shot but back up your world before opening it.

If it does work, though, make sure to notify your players (and maybe reimburse them)

Used Midas Gold to convert quarries into sponge blocks.

I then set up an admin shop on the server where you could sell this sponge block for Credits.
