How are diamonds mined? A look at the global supply chain

17/10/2018  The Jubilee mine in Sakha, Russia, uses an extraction method known as pipe mining. This involves embedding shanks into long cylinders of kimberlite ore, known as ‘pipes’, and digging up large amounts of soil. This soil is then transported off-site, where it is processed at specialised facilities to separate rough diamonds from the majority of the soil. The operations have been effective, as Jubilee

Types of Drilling Methods used in Mining Boring

Diamond drilling method is suitable for drilling at any angle to obtain cores of friable strata as well as the hardest rock. It has been adopted for drilling upto a depth of 3000 m and hole diameter upto 200 mm. Drilling upto such large depths is not required in coal mining areas where the maximum drilling depth is upto 1000 m, as coal mines are rarely deeper than that.
