"In the past decade, when they were closing collieries, I seem to recall some were said to have been mothballed"

I think Whupsy and the other miners on here will know more, but as I understand it, to mothball a pit, is quite an expensive thing too doo, because it means that the pit must be kept clear of water, by constant pumping, and quite a lot of other stuff needs to be done to keep the pit healthy, and once the pits have closed, they fill up with water, and the tunnels collapse, so they cannot be opened up again, another pit would have to be sunk to resume coal production.
