Starting with the shallowest the following seams have been mined and totally extracted from the around the site (year in brackets = approximate date of activity):
Hutton (1950s) c. 10m below site
Harvey (1945) c. 110m below site
Tilley (1940) c. 112m below site
Top Busty
Bottom Busty (prior to 1910)
Three Quarter (1890s?)
Brockwell (1900)
The Hutton seam was extracted using the opencast technique whilst the others were all underground.
The site of the new creative media centre is marked with the red dot on the Coal Board's plan of the Harvey Seam. The hatched area is coal fully extracted and the grids of lines are areas of 'room and pillar' extraction.
