SEM Concrete Pumps underground - Job References
| Mine: | Blyvooruitsicht Gold Mine, South Africa |
| Type of Work: | Construction of Underground Pump Station |
For mining reasons it was found necessary to re-site the underground pumping station at No. 4 shaft. The projected amount of concrete to be placed was close to 6000 m³.
The mine purchased a SEM 200/100 Concreting Unit to do the concrete mixing and placing. In the words of the Foreman/Fitter in the Engineering Department:
"We have to date mixed and pumped concrete with the SEM Unit for approximately 2 500 hours with an average output of 2 m³ per hour. We have pumped the concrete into all our new settlers, dam walls and pump foundations over distances up to 100m. A lot of the pumping took place downhill, which compared with horizontal pumping, can be problematic, unless you know what you are doing."
He further adds: "On the next job I definitely will have the SEM 200/100 Concreting Unit along. It is now hard to visualize doing the concrete work without it".

| Mine: | Most South African Mines |
| General Information: | General Day to Day Concreting Work |
In all underground mines there is a certain amount of concrete work that has to be done - whether it is of an occasional or day-to-day nature. The relatively small amount of concrete required does not economically or practically allow a piston type pump to be used. The conditions are difficult and can normally only be solved by slow and labour intensive methods or by employing concrete pumping or placing.
The set-up illustrated below is a typical one for an application that occurs every day in a South African mine. SEM supplies single pumps (placers) in 3 different models, or combination units of mixer/pump that caters for work where frequent mobility is required. The work may consist of a short horizontal line as depicted or pipe lines going up and down shafts involving distances of hundreds of meters.
