Location
This part of West Yorkshire, between Leeds and Castleford has
been extensively deep-mined for coal since the late 1800s and
there have been several opencast coal mines since the 1940s.
The initial St Aidans site was extended in a new contract that
started in 1981 and was expected to yield about 6m tonnes of
coal from a number of different seams over 10 years.
River Aire
The River Aire formed the western and southern boundary of St
Aidans Extension, with the canal running close-by.
Part of the river was diverted and a 4m high flood levee was
constructed along most of the river next to the site.
Steel sheet piling was driven, generally down to rockhead, to
further strengthen that the area between river and site and to
prevent groundwater flow.…read more
