Blasting with gunpowder enabled larger quantities of rock to be broken, but it was also a risk for those involved.

Many miners were injured or killed when charges went off early, or when they returned to re-light fuses, which were often unreliable and made from goose quills. In the modern mine, rock was blasted using gelignite, a much more powerful explosive.
