Hi,

In this changeset and the previous one, you added objects and tagged them as chimneys. They are not what OpenStreetMap defines as chimneys (removal of smoke/gases)

https://wiki.openstreetmap.org/wiki/Tag:man%20made=chimney

They are Ventilation Shafts (create flow of air in a space such as a mine or tunnel)

The lack of connection in the Wiki pages are not helpful. So I'll make a change.
