Debswana investigations of Jwaneng mine slope failure

Months after the slope failure that claimed the life of an employee at Jwaneng mine, Debswana is still undertaking several technical investigations to enable them understand the geological make-up of the rock structure and how it could have interfaced with any other causes to result in the slope failure.

Jwaneng mine accident: report reveals how Debswana

It has also emerged that the slope failure at Cut 6 occurred at a high risk area identified three years ago by management reports. Despite complaints from miners, “the only attempt made to stabilize the area appears to be the placing of supportive ropes in the area. This has proven to be insufficient by the current fatal slope failure.
