Coal mines

The late 18th century was the start of deep coal mining in the UK, with rapid expansion across the Uk. Northumberland and Durham were the biggest coal producers with their pits being a huge 300 ft deep.

Small groups of miners were working part time using shovels and other equipment to remove the coal, before the 1800s coal was left around the pillars to support the mine. This meant a huge amount of coal was left to prevent cave ins. Wood props were introduced to support the roof, the most important part of safety was the control of fresh air and explosive gases.
