Coal minings advent in South Africa can best be traced to the start of gold mining in the late 19 th century, particularly on the Witwatersrand, with the first coal in appreciable tonnages being extracted on the Highveld coal field close to the nascent Witwatersrand gold mines. However, demand began to grow, slowly at first but then exponentially as the country entered a period of industrialisation during and
