I partly agree...
landuse=mine is an undefined Tag, so it is not clear what is meant here. 
In case of underground mining I would agree to have it being a subtag of 
landuse=industrial, as the surface installations could be of a similar 
category. In case of surface mining however it is a characteristic of 
its own, which comes close to quarry. However furthermore I would prefer 
to have it the other way round, quarry being a special case of 
surface_mining:

landuse=surface_mining
resource=limestone, marble, sand (or whatever)
(which implies a quarry)
