Coal production began from the Haigh Moor Seam in 1895 and from the Silkstone Seam in 1897. In 1900 there was a visit from the British Association. The booklet printed to accompany the visit gives the output at 2,700 tons per day, the mine employed 2,200 men and boys and 160 horses, and owned 1,600 railway wagons. This photo was printed in the booklet.
As the underground workings got further away from the shaft in Featherstone it was decided to sink another shaft at Ackworth and install a ventilating fan. Sinking commenced in 1912.
By 1924 the pit was at its peak employing 1,940 men underground and 636 on the surface. This photo shows one of the more than 2,500 workers, one of the 1,600 coal wagons and one of the 160 horses and pit ponies.
