Diamond Mining Methods Diamond Museum Cape

There are two types of pipe mining, namely open-pit mining and underground mining. Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore.

Williamson Mine (Mwadui mine; Mwaudi kimberlite

Williamson is an open pit operation based upon the 146-hectare Mwadui kimberlite pipe, which is the world’s largest economic kimberlite to have seen continuous mining. The Williamson mine was discovered in 1940 by Dr. John Williamson, a Canadian geologist, and is the largest economic primary diamond deposit to be in continuous production.

Lucapa envisages mining the kimberlite in two phases. Phase 1 will include the weathered kimberlite material at the top of the pipe while mainly the underlying harder and unweathered kimberlite is planned to be mined during Phase 2. Mining by conventional open pit methods such as drill and blast followed by load and haul will be employed.
