Emalahleni is the centre of coal mining in South Africa. Coal mining began here in 1890 and soon thereafter the government proclaimed Witbank (today Emalahleni) as a town in 1903 (Campbell et al., 2017). The Johannesburg-Delagoa Bay (today Maputo) railway line was crucial in the development of the town.
