The flue extends down the slope from the chimney and terminates at the side of the lane.
Llay Hall Colliery operated from 1877 until 1948. It was sunk by the Llay Hall Coal, Iron and Fireclay Company and worked in association with a fire brick works on the opposite side of the River Alyn. It was nationalised in 1947 but closed shortly afterwards, following a serious underground explosion. The chimney and flue serviced the steam boilers for the colliery and probably date from the 1890s.
The chimney is of square section in red brick, and tapers slightly to a height of approximately 25-30m. There are corbelled bands around the base and just below the top. The flue extends in a straight line for approximately 50m to the north, beginning just below ground level and then constructed on the surface following the line of the slope to the bottom. At the edge of the lane it passes through a stone cross-wall and comes to an end near the former position of the boilers. The flue is built with vertical side walls of red brick with a concrete slab top.
Listed as a particularly fine example of a colliery chimney with an unusually long approach flue. The chimney is a prominent local landmark and has group value with the associated former colliery buildings.
