SYNOPSIS

The purpose of the investigation was to assess various options for increasing the efficiency of the conveyor belt transporting system used at 4 Belt Shaft at Lonmin's Marikana operations. The reason for the investigation was to prevent the occurrence of a 'bottleneck' at the main ore passes delivering ore to the conveyor belt system, thus creating more fluent operational conditions. The options assessed for increasing the efficiency of the conveyor belt transporting system were:
Variation of the conveyor speed
Concurrent tipping from two ore passes on the belt
Increase the available drive unit power
Increasing the feed rate from vibratory feeders
Change in belt width/belt specifications
The report shows that the most preferable option to the current situation at 4 Belt, Lonmin, would be the option of concurrent tipping from two ore passes to the belt.
