While the deepest ore can be found at the shallow depth of 500m below surface, unusually hot ground water at temperatures of up to 55°C is a challenge. BBE was asked to assist with the original mine design, and it was clear from the start that mine cooling would be required to provide acceptable underground temperatures. Advertisement
Steven Bluhm. Mine ventilation can account for 30% to 40% of some deep underground mines' total electricity consumption. Taking that into account, a variety of energy management options offer significant scope for improving mines' electricity consumption profiles. Traditionally these mines have been ventilated and cooled on the basis of all-the-mine all-the …
Whilst gold's decade-long bull run appears to have come to an end, African production proceeds surely and steadily. MJ Morgan presents his monthly mining news round-up.. Investors have withdrawn their money from gold, as the global economic recovery continues and fears of further crisis recede.
Mining Weekly reported that China National Coal Group will use a special cooling technology developed at a gold mine for its coal mining operations.

1. Kibali, DRC. 808 koz. Kibali is the biggest gold mine in Africa, located in the northeast of the Democratic Republic of Congo (DRC), approximately 220 kilometres east of the capital of the Haut Uele province, Isiro, 150 kilometres west of the Ugandan border town of Arua and 1,800 kilometres from the Kenyan port of Mombasa.

Ice cooling takes the heat off at Harmony's Phakisa gold mine. Two and a half kilometres below ground, rock temperatures top 50oC, and keeping mines – and miners – cool soon becomes both essential and expensive. Dr Gareth Evans reports on the new approach to 'ice cooling' currently in use at Harmony's Phakisa gold mine in South Africa.
Strong assets have positioned Pan African Resources as one of South Africa's high-margin gold miners. From one of the oldest and richest working gold …

Delays to the Phakisa mine cooling system Harmony Gold Mining Company had commissioned ice-making plants to cool their 2.4 kilometre-deep Phakisa mine. When they discovered the plants wouldn't be ready on time, they asked us to step in and find a way to bridge the gap, fast.
Deep gold mining cooling with ice Posted by Matrix on 26th August 2014 In South Africa, where gold extraction can be from 2,400 m below surface (and much deeper at some mines), the rock temperatures can be greater than 50°C.
Mponeng is a gold mine in South Africa's Gauteng province. Previously known as Western Deep Levels #1 Shaft, the underground and surface works were commissioned in 1987. It extends over 4 kilometres (2.5 mi) below the surface, and is considered to be one of the most substantial gold mines in the world. It is also currently the world's deepest mine from ground level, reaching a …
With many of the deepest mines in the world, cooling and ventilation has been indispensable to safe operations in South African mines for decades. It's a non-negotiable consideration in every stage of the mine's growth and lifecycle. However, in Mexico, mines are only just starting to grapple with the issue. Two recent projects by BBE in ...
