The Sishen mine is a large iron mine located in central South Africa in Kathu, Northern Cape. Sishen represents one of the largest iron ore reserves globally having estimated reserves of 2.43 billion tonnes of ore grading 58.6% iron metal.
We were tasked to setup dust monitoring (particulate matter) PM2.5 and PM10. The solution consisted of fixed and mobile stations mounted on trailers with installed data loggers.
Data is also sent to the cloud server via GSM and can be remotely accessed through a Windows application. The bulk of the stations are solar-powered due to lack of accessible power where they are situated around the mines.
