In order to meet export sales requirements from 1983 onwards, Amcoal developed a new underground mine in the Witbank area of the Transvaal. The mine was required to produce 5 million tons of run of mine coal per annum giving rise to 4 million tons of saleable products. A description of the coal processing plant is given with comments on design philosophy and design parameters. Main features of the coal processing plant are the raw coal handling facilities, centralised control and data capture and the loadout station. The management systems applied during the commissioning period are described. The difficulties experienced and their solutions are discussed. Commissioning was concluded with an independent plant performance test.
