Here is the second template showing a black and white outline of a coal mine.
Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on the depth and thickness of the coal seam and the density of the overburden. A coal mine and its structures are called a “colliery”, which is shown in the picture.
Mining allows for coal, the fossil fuel sometimes called black gold, to be extracted.
This template could be used for presentations on Welsh coal mines, the miners’ strike, history, geography, steam, global warming / climate change, depression, industry, machinery, pre-war and 1920s-1930s.
