The mine planning process for an openpit 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 . diamond mining, mining of diamond, diamond, diamond ...
OpenPit Mining. Doctoral dissertation. ISBN . ISSN .

What is open pit mining . Open pit mines are those mining operations that take place on the surface, unlike the underground mines. This is possible when the reservoir sprouts on the surface or at a very small depth. It began to be realized in the middle of the XVI century and it is used all over the world. In order to be carried out, the excavation (using machinery or explosives) of the lands ...
· An Overview of the Open Pit Mining Process. Openpit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling.
OPENPIT MINING Openpit mining, such as the Kimberley Big Hole, involves removing the layers of sand and rock found just above the Kimberlite. The ore in the pit is then broken up by blasting.
