Are you offering to pay all those subsurface property owners for their property that you are trying to steal?  I didn't think so and that is a KEY component of eminent domain.  But the courts and ANYONE with common sense at all knows that a ban on extractions and restrictions that prevent any extraction are the same exact thing no matter what you call them. 

And no the Courts have ruled repeatedly that cities and counties and municipalities DO NOT have the right to regulate this area and they have done it with other areas as well.
