'A voyage of discovery offering endless horizons' (Mrs Robson)





A new colour palette brings in more strands and now includes gloss black (coal), bright green (landscape), yellow (historic landscape perhaps in the shape of whin blossom) and red for the outline of the Ord/Capper land on the old plans.



Close to the site is Nanny's Nursery - a narrow strip of trees (large oak and beech mainly) that continue the hedge line over the brow of the hill. There are a lot of larger boulders amongst the grass here which belong to the natural geology of the place - a rough sandstone I think. I found coal here too - maybe a co-incidence but surely this is left from the mitigation work done after the mining.


Opencast mining for coal as we know it today started in 1942 as a wartime expedient. To boost vitally needed coal output, surface mining became the responsibility of the Mines Department of the Board of Trade and was carried on by the Ministry of Works until 1945, then by the Ministry of Fuel and Power.
In 1952 the National Coal Board, now British Coal Corporation, was given responsibility for opencast coal production and the Opencast Executive was established.
In the early years opencast operations were limited by the size of the excavating plant then available. Maximum depths were only about 10 metres and ratios of strata above the seams — overburden — to coal were restricted to about 5 to 1. Over the years, however, there were substantial increases in the size of plant and by 1948 the maximum depth of excavation had increased to 30 metres.
