The surface communications system at Mafube was split into two sites – one at the tip areas, consisting of three voice repeater stations, and the other on the silo consisting of five repeater voice channels, Mine Radio Systems president Ken Morell said.
“Communication for the mine site was essential for production, safety and for the various departments on site,” he said.
Once the initial surface communication systems were installed, MRS began installation of two systems for pump control and pump monitoring.
MRS South Africa general manager Richard Tagge said: “The pump control and monitoring system allows the mine operators to maintain control over the amount of time the pumps operate, which will help increase their profits.”
With expansion at the colliery expected, MRS was also contracted to install a link communication system to the pit area.
Mafube is a 50:50 joint venture between Thermal Coal and Exxaro and is situated about 37km east of Middelburg, Mpumalanga.
The colliery started out as a mini-pit operation in June 2004, to supply coal to Eskom’s Arnot power station. Since its final commissioning in January 2008, it has grown to produce an annual 2.5 million tonnes of low ash coal for export and 1.7Mt of steam coal for the domestic thermal market.
MRS South Africa has seen an increase in profits from the installation of its communication, safety and monitoring systems throughout Africa.
The market movement towards increased safety, advanced monitoring and control has been the major reason for the successes in market share, according to the company.
MRS South Africa was poised to have one of its best years to date due mainly to increased product innovation, it said.
