The mine is near New Mill, West Yorkshire.
Since my last visit about one month ago I have noticed that the old brick buildings have been partly demolished so now there is only one partly standing. Whether it is the owners or brick theifs I don't know.
I have been today to take a member of this forum whose father used to work there. There appears to be another entrance to the left of the existing one in the next field behind a barbed wire fence forming a water course. The mining maps show two entrances.
The access tunnel behind the concrete block wall is about 670mm wide and 900mm high with stone side walls and vaulted stone roof.
This mine is linked to Snowgate Head colliery and Wood Pit and many others in the valley. My friend found out today that donkeys to the mine used to go into the Wood Pit entrance
