Ekati Diamond Mine, NorthWest Territories, Canada ...


Openpit mining started on the Panda pipe and Koala, Misery and Fox pipes were sequentially developed, between 35Mpta and 40Mtpa of waste rock excavated from the pits. The ore is processed at the 18,000tpd processing plant. The Panda Diversion Channel diverts water around the Panda and Koala Lakes into Kodiak Lake.

The Mining Life: Open Pit vs. Underground MICROMINE


Working underground is usually a hot, noisy, humid, and dark business, but working in an open pit mine can expose workers to weather conditions, which can cause problems as well. Working in the mining industry in any capacity is hard work that demands exceptional concentration and talent in order to stay safe in the environment of heavy materials, heavy equipment, and hard work.

OpenPit Mining Methods


Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit ...

Opencast Mining an overview | ScienceDirect Topics


The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can be sustained. There are many advantages to the open pit mining method, namely: 1.

What is opencut mining? Oresome Resources


Opencut mining is one method used to extract these minerals from the earth. Opencut mining is used when the minerals are found over a large area and relatively close to the surface. The open cut mine is dug downwards in benches or steps which slope towards the centre of the pit. To uncover the minerals the land is first cleared of vegetation as

Environmental Risks of Mining


Environmental hazards are present during every step of the openpit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestoslike minerals, and metallic dust.
