Bentinck colliery, 1911. Owned by the New Hucknall Company, Bentinck (Kirkby), also the family name of the Dukes of Portland, started production in 1896. It was the first British colliery to produce one million tons in seven months, and in 1978, 20 acres of barley was grown on the tip. By the 1980s the screening sheds at Bentinck were part of a modern coal preparation plant which also processed coal from Annesley and Newstead. Most of the output went to Ratcliffe Power Station. In April 2000 the winding wheels were purchased for £100 and taken to a mining heritage centre at Newcastle under Lyme.
