The mines stayed in private hands till the industry was nationalised in 1947. A major development in coal mining took place in West Cumberland in 1650 when, to win new tracts of coal, pits were sunk and drifts cut horizontally from the lower grounds to drain the workings. This arrangement was called the pit and adit system.
