Location: Ghana | Client: Howden Africa

Maboneng Precinct

Project Description

Howden Africa engineer and construct, among others, systems for mine ventilation. Their product line includes some of the largest surface mine ventilation fans in operation, as well as smaller fans for auxiliary and booster applications.

Greene Consulting Engineers (Pty) Ltd was approached by Howden to design the foundations of the surface mine ventilation fans. This would allow them to offer a turnkey solution to their clients. The fact that Howden’s product offerings can be customised and are constructed in all types of difficult mining environments drives Greene to design creatively. Dynamic analysis of the foundation structures is of the utmost importance. The varying ground conditions and equipment operating frequencies influence the natural frequencies of the structures and, therefore, the variations in designs.
