project description

The contract, awarded by Cmc in joint venture with Bomar Project Pty, a South African company, regards the development of an underground copper mine, owned by the Konkala Copper Mines, the largest copper producer in Zambia.

 

The contract involves the excavation of the access tunnels and muck at two levels of abstraction (called 2900L and 3150L) respectively about 880 and 960 m. depth and accessible through the extraction wells. The tunnels, dug with the traditional method, will have size of 5.50 m. to 5.50 m.

 

The contract also includes the shafts that branch off from the access tunnel that will reach the various levels of the geological structure with the copper ore.

 

These shafts have a size 4.20 x 4.20 m. The total length of the tunnels to be excavated is about 63 km.  The estimated amount of material to be excavated is approximately 1,200,000 m3.
