Richard Gundersen has over thirty five years’ experience in the fields of mine ventilation/refrigeration and hoisting. He joined BBE in 1999. BBE is a specialist consulting group in the field of mine ventilation, cooling and refrigeration covering all aspects of work from basic and applied research, through feasibility studies, detailed system designs, cost estimating, detailed engineering design, to project engineering as well as investigative and improvement work on existing systems. Richard was a major contributor to the ventilation and refrigeration part of the Deepmine research project. He has been responsible for the upgrade of refrigeration systems at Amandelbult, Northam and Driefontein.

Previously Mr Gundersen was Consulting Mechanical & Electrical Engineer at Gold Fields of South Africa, responsible for the engineering functions throughout the Group.

Responsibilities included:-

  • Mechanical and electrical engineering associated with hoisting throughout the Group;
  • Managing a team of technicians conducting routine and special inspections on winding plant;
  • Electrical engineering functions for the base metal, coal and platinum divisions;
  • Mechanical and electrical engineering for the Group’s Namibian operations;
  • Project Engineer for the installation of a new furnace at Tsumeb;
  • Consulting and design engineer for the Group’s winding plant – operating and new;
  • Identification and introduction of new technologies, e.g. cycloconverter drives, hoisting configurations;
  • Improving the efficiency of existing hoisting systems, e.g. rope selection, scheduling;
  • Group representative on research/advisory bodies: winding rope development, winder codes;

Other positions include Assistant Consulting Electrical Engineer; Assistant Consulting Engineer (Ventilation) and Group Engineer (Refrigeration) within Gold Fields. In these positions he was the Project Engineer for new plant installations with values up to R200 million; the Systems Design Engineer for integrating new technologies into the mining environment and for optimising efficiency of system layouts. He has presented and published papers on the benefits of hydro-power for deep hot mines; the hidden costs for operating diesel-powered machinery at depth; energy-efficient systems designs. He has been the industry representative on several research advisory and regulatory committees to improve the viability of existing mines and the feasibility of deep level mines.
