Diamond Mining Methods | Diamond Museum .
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 can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into ...

In 2006 and 2007, another group of bulk kimberlite samples was collected underground at each of the three pipes (A154, A418, and A21) to determine underground mining conditions, to compare the impact of drill and blast mining versus machine mining on diamond value, and to provide about 15,000 carats from each pipe for additional estimations of rough diamond values. With the exception of the ...
A Comparative Study of Ground and .
With the increase of open-pit and underground combined mining and the occasional need of open-pit mining, several underground workings may be located in close proximity to an operating open-pit mine. In these cases, ground vibrations generated due to open-pit blasting may be hazardous to the stability of adjoining underground workings as well as surface building structures and residences 11 ...
Open Pit Mining Pros & Cons | Sciencing
Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred. Today, with safer mining processes, such as open ...

All-in sustaining costs and all-in costs | World .
It is important to note the due to the differences between US GAAP and IFRS, under which IFRS permits the capitalisation of deferred stripping costs for an open pit mine in production and US GAAP does not, US GAAP reporting companies can typically experience a higher level of NRV write-downs for mines during stripping campaigns because all stripping costs flow through inventory costs.
Environmental Risks From Mine Tailings - .
Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings. Tailings can reach immense proportions, appearing in the form of large hills (or sometimes ponds) on ...
