Coal was discovered as a useful resource for multiple developments like that of machines, pipelines etc during industrialisation. This gave birth to the problem where while mining coal, the mines used to get flooded. This was in turn solved by the invention of the steam, using which Thomas Slavery made a steam engine called the Miner’s friend to pull water out of the mines thereby preventing the flooding and solving a problem that threatened the lives of the miners.
