"Female Employment at the Coal Mines
It was not uncommon for them to employed underground, which was made illegal after 1842. They were certainly employed underground in the collieries of Scotland, Cumbria, Northumberland, Shropshire, Yorkshire and Lancashire. In Scotland and Northumberland they often carried coal in baskets on their backs, to climb stairs out of the mine. Elsewhere, they hauled waggons on all fours, by means of a chain around their waste, through low passages. In Silkstone, near Barnsley, women and girls died in a mine explosion in 1805, and a further seven (9 to 17 years old) died in a tragic flooding of the Moorside Pit in 1838. In 1841 there were 2350 women employed in the coal mines of the UK, one third of them in Lancashire. After 1842, the women and girls worked at the surface, pushing wagons from the pit head to the sorting screens, or sorting coal at the screen themselves. In some mines the latter continued until the 1930’s."
This is yet another area where history is rewritten to fit the views of whoever wants to make an argument
Women's roles being written out of history in general is an issue and always has been.
