Kefid · 1968. Mining commenced in 1972 and is still carried out to date. There are two waste dumps in close proximity to the two open pit mining operations. The paper covers the slope stability analysis of the active dump as mining expands and the dump develops further. A phased rehabilitation programme will be implemented on the inactive dump.
