The four most commonly used diamond mining techniques are: Open pit mining – Mostly used in sandy areas or places with unstable grounds, this involves digging a large open pit in the earth’s surface to extract diamonds. It is said to be hazardous to the environment. Hard rock mining or tunnelling – Vertical and horizontal tunnels are
Jan 08, 2020 RCT says it has installed its ControlMaster Line-of-Sight solution on equipment at an open-pit diamond mine in South Africa. In 2019, RCT installed and commissioned the solution on a CAT 994 wheel loader, which has been utilised to clear pit benches of debris falling from the crest of the bench above at the mine, owned by a major mining company, RCT said.
Open pit mining is easier since it is done of the surface of the earth rather than below ground. It is hard to predict which type of mining is more suitable for a given site, so a lot of analysis must be done on the land around a site before anything begins. Diamond mining, like diamond exploration, is a very costly operation and can take many

ground: open pit mining and underground mining. In open pit mines, workers remove waste rock and earth to get to the kimberlite pipe using digging equipment and explosives. In underground mines, spiral-shaped tunnels are built to allow mining equipment to drill, blast, dig, and haul the ore from deeper parts of the kimberlite pipes.
The mine planning process for an open-pit diamond mining operation the two pipes is shown in Figure 3. A 2012 resource extension drilling program has increased the confirmed vertical depth of the kimberlite pipes to 793 m and 828 m for the Main and Satellite pipes respectively (Figure 4). The surface expression of the Satellite Pipe is

The steepening of slope angles on an open pit mining operation has a material impact on improving the economics of mining. Steepening of slope angles can also increase the risk of slope failure. Slope failures are inherently costly events, because they can be catastrophic, resulting in multiple fatalities, equipment damage, and temporary or
The 2.6 Mt/a open pit mine and processing plant produces approximately 380,000 carats/annum of gem quality (including Type IIa) diamonds which are sold through regularly scheduled tenders throughout the year.

Diamond Mining and Prospecting. Diamond is unusual as a target for mining because it is found in igneous/explosively emplaced rocks, and the diamonds are carried up with these rocks from the Earth's mantle. Apparently the depths are somewhere in the vicinity of 160 km (100 miles) below the Earth's surface. The diamonds can then be mined in this
