The mine practices conventional mechanized mining deployed with Hydraulic Excavator of 2.6 m 3 bucket capacity in conjunction with 40 T haul trucks, one rock breaker & two drill machines of 115-mm diameter each. The overburden bench is prepared by drilling and blasting after the topsoil has been excavated to a thickness of 1 to 6 m.
In 2015, after amendments to the explosives regulations, stemming became a mandatory activity for all South African mining operations. There are, however, circumstances in which it is thought stemming has an adverse impact on the blasting outcome. Some of these circumstances include blasting in hot holes, in reactive ground, or when blasting a pre-split. In order to determine …
