Canceling mine/extractor queue?

[GI Seve]

So how to cancel order of build mine/gasextractor?
The building itself has not yet started as it is on queue. Nothing on manual says a thing about this one and couldn't find anything relevant on search.

Pull up the list of constructors from the toolbar on the left, find the constructor with orders to build the mine, and tell it to stop or do something else.
