    Abstract. The continued fall in the output of coal from deep, or underground, mining in a period of growing demand for war purposes, both internal and external, and the necessity for maintaining as far as possible the supply for domestic purposes during World War II led to the exploitation by opencast methods of those deposits of coal which occur at, or relatively near to, the surface.
