There are two types of pipe mining, namely open-pit mining and underground mining. Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting. A single blast
To safely open-pit mine the kimberlite, water retention structures (dikes) were constructed in the lake to hold back the lake waters during mining. The main cost advantage of open-pit mining is that it allows mining with more efficient larger equipment. This means faster production and mining

For kimberlite pipes of yakutia appropriate boundary surface mining to determine the technical capabilities used for open pit mining equipment, and based on the actual received indications of its use with regard to large downtime on climatic conditions, lack of quality maintenance in the biting cold, which leads to premature wear of mining.
The Chidliak diamond resource, a cluster of at least 74 kimberlite pipes, was discovered on Nunavut's Baffin Island in 2008. Peregrine Diamonds and BHP Billiton, the world's largest mining company, were working together to develop the project. They hoped to start an open-pit mine in 2020, but they had a huge transportation problem.
Four small diamond pipes (B/K1, B/K9, B/K12 and B/K15) were discovered between 1967 and 1972 in an area 20km east of the Orapa kimberlite pipe. These pipes were grouped to form the Damtshaa Mine, the youngest of the Debswana mines which began operation in 2003, and are managed along with Letlhakane Mine from the Orapa operation.

Mining diamonds with specialised tools. We use advanced diamond mining technology and huge earth-moving equipment to bring diamonds to the surface. In our open-pit mines, trucks with 250 tonne payloads and tyres twice as tall as an average man carry diamond-rich kimberlite
After dewatering of the 30 m deep open pit excavation made by Sierra Leone Selection Trust and the National Diamond Mining Company in the 1970s and 1980s, removal of the remaining silt and mud commenced. Between March 2003 and November 2003, the No. 1 Pipe was dewatered, cleaned and prepared for the conventional open pit mining phase. No. 1 ...
Open Pit Kimberlite Pipe Mining Equipment. Open pit mining involves removing the layers of sand and rock found just above the kimberlite once exposed the ore in the pit is broken up by blasting a single blast can break approx 3 000 tonnes of ore once the ore is broken excavators load the ore.

The kimberlite is extracted in enormous quantities using huge trucks and giant steam shovels; the pipe is mined from the surface as an open pit. When it gets too deep, underground mining may begin. Because of the huge quantities of rock involved, the mining

These images are from the largest open pit gold mine in Australia. The Fimiston Open Pit, known as the super pit, located in Kalgoorlie in Western Australia. The Pit stretches 3.8 kilometers by 1.35 kilometers wide at the surface. And it goes down to a depth of 500 meters. Another example of very large open pit
While alluvial mining requires waiting for diamonds to first rise up through kimberlite pipes and be washed away by erosion to settle on river or ocean beds, pipe mining allows diamond miners to strike closer to the source—the kimberlite pipes. Pipe mining has two forms: open-pit diamond mining and underground diamond mining.

The pipe is dug in tiers from which the materials to treat is put into trucks. Underground Mine. The underground mine can today reach depths of more than 1,000 meters. The content of diamonds is decreasing with the depth. Underground mining is more expensive than open-pit mining and requires more complex management and machinery.

2020-5-31Open-pit operations on the two ore bodies of the A154 pipe began in January 2003, and mining of the A418 pipe followed in 2007 figure 9. This type of mining was economically viable because the tops of the kimberlite pipes were within 20 meters of the surface, minimizing the amount of waste rock that had to be stripped away to expose them.
Underground mining has exploited remnants of the pipe left from the open pit from the 244-m elevation. A generalised section of the pipe, the mined-out open pit, the shaft systems, and the major development tunnels are shown in Figure 54.3. As mentioned previously, internal waste comprises about 20% of the pipe

It is considered that vertical pit mining is a viable alternative to conventional open pit mining and can effectively be exploited on small to medium sized kimberlite pipes.
