This mine is owned and managed by BHP Billiton. Although drilling at Wessels as early as 1951 exposed manganese ore, the true extent of the ore was only proved in 1966, when deeper drilling was undertaken.

Production

Wessels mine is an underground operation situated 300 metres below the surface. Access to the workings is achieved by means of a vertical shaft and two incline shafts. The nature of the ore body lends itself to a mechanised room and pillar mining method.

The ore is broken by means of drill and blast methods. Mechanised electrically powered drill rigs drill horizontal holes into the face. These are then filled with either ammonium nitrate or a nitro glycerin explosive and blasted to minimise the generation of fines (-0.5mm).

Front end loaders, matched with 25 ton dump trucks, load and haul the ore from the faces to satellite crushers underground. The ore is then conveyed to underground storage silos where it is temporarily stored before a cable belt conveyor transports it to the surface for washing and screening.

Ore is screened into different size fractions in a wet screening plant on the surface. The different size fractions are sampled and stockpiled according to grade and size fraction. These stockpiles are loaded to the trains, either as a whole, or blended to meet customers’ requirements.

  • i wish to work at Wessels mine.Because is the dream that i have been before.sampling/Drilling assistant and Laboratory(analys chemistry
  • I am a mining engineer and Professor in Mining in India. I would like to know the geological and mining characteristics of the ore body, hydro logical problem, the mining method/s the ground control system, the stope size its stability characteristics, yearly production rate... and such salient details
