:: Bateman Completes 21 Km Overland Conveyor System  

In March 2002 Ingwe awarded Bateman a turnkey contract for a 20,9 km overland conveyor system to be supplied to Optimum Colliery. The contract includes all design, supply and erection, inclusive of civil work. The system is comprised of 4 overland conveyors plus the upgrade of an existing 6,1 km conveyor.

Optimum Colliery is a major coal mining operation in the BHP Billiton Energy Coal Group, situated in the Witbank Coalfield area of South Africa, producing coal for the South African domestic market and exports through the Richards Bay Coal Terminal. Named the Kwagga Project it accesses approximately 200 mt of coal reserves, adjoining the existing operation which will be accessed via this new overland conveyor system.

Phase 1 of Bateman's contract was completed on schedule in January 2003 and work is well underway on the 3,8 km Phase 2 scheduled for completion in May 2003.

Of particular note was the upgrading of the existing 6,1 km conveyor which was originally built in the 1980's. Conveying 1 200 tph of Run of Mine (ROM) coal on a 900 mm belt it was required that Bateman increase this capacity to 2 700 tph. The final design retained the existing structure and doghouse sheeting and replaced the existing belt with one of 1 200 mm width.

The existing drive houses at the tail and head end of the conveyor, together with the belt turnovers and chutes were removed and replaced with completely new structures in keeping with the higher tonnage and belt speed of 6,9 m/sec.
