I stumbled across your website recently, some really interesting stuff on there! We are still heavily involved supplying industrial coal in the UK. Thought you might be interested in the pics from Eckington Colliery (New). I took these on what I believe was the last time the mine was entered prior to being sealed up. Prior to this we took most of the coal there in the previous years.
Sadly all the kit is still down there, though we have the remains of the bobcat loader and dreadnaught cutter in our yard.
Pics taken 11th January 2019.
All the best
