Walker Fan House and Drift

Walker Fan House and Drift

Situated between the Institute and Platt shafts the fan extracted some 43,000 cubic metres of air per minute, which entered the mine via the Hesketh and Winstanley shafts and exited through the Evasee up the Platt and Institute shafts. It is estimated that the air travels 37 miles once it enters the underground workings.
