Before the eighteenth century, Britain — and the rest of Europe — had produced coal, but only in a limited quantity. Coal pits were small, and half were opencast mines (just big holes in the surface). Their market was just the local area, and their businesses were localized, usually just the sideline of a larger estate. Drowning and suffocation were also very real problems.
During the period of the industrial revolution, as demand for coal soared thanks to iron and steam, as the technology to produce coal improved and the ability to move it increased, coal experienced a massive escalation. From 1700 to 1750 production increased by 50% and nearly another 100% by 1800. During the later years of the first revolution, as steam power really took a firm grip, this rate of increase soared to 500% by 1850.
The Demand for Coal
The rising demand for coal came from many sources. As the population increased, so did the domestic market, and people in town needed coal because they weren’t near to forests for wood or charcoal. More and more industries used coal as it became cheaper and thus more cost-effective than other fuels, from iron production to simply bakeries. Shortly after 1800 towns began to be lit by coal powered gas lamps, and fifty-two towns had networks of these by 1823. During the period wood became more expensive and less practical than coal, leading to a switch.
The iron industry began to relocate to coal fields, which usually had iron ore nearby. Developments elsewhere also helped to boost iron by stimulating demand, such as the increase in steam engines (which needed iron), which in turn boosted iron innovations as one industry bred new ideas elsewhere.
