The average depth of metal mines in South Africa has reached 2000 m, and the Western Deep Level gold mine has reached 4800 m [3]. Deep rock mass is characterized by high in situ stress, high temperature, and high water pressure.
Working conditions become increasingly hostile as depth increases. In the Witwatersrand gold mines of South Africa, special acclimatization programs were
Increasing demand for metals caused by global economic growth and exploitation of shallow mineral deposits forces mineral extraction to go deeper. A direct
In a world of deeper mines, more complex ore bodies, rising energy costs, social and geopolitical risks, infrastructure shortages and resource nationalism, mining
Human Capital Considerations. Perhaps the greatest concern now facing the gold industry is the degree and rapidity of shrinkage in personnel. Chart 3 reveals that, over a twenty
Below we explore 5 challenges currently facing the industry. 1. Access to Energy. As resources in some areas become scarce or depleted, companies are forced to push new frontiers of exploration.
With more than 66% of all new mining exploration in the hardrock sector currently focused on gold, the problems are going to get worse for people and places

Increasing demand for metals caused by global economic growth and exploitation of shallow mineral deposits forces mineral extraction to go deeper. A direct consequence of this development is an increase in rock pressurerelated mining problems. The role of rock engineering in the design and operation of deep mines is discussed in
Gold miners are facing a reserves crisis, and what is left in the ground is becoming more and more challenging to process.Refractory gold reserves, which require more sophisticated treatment methods in
The gold mines in India will enter depths of 2000–3500 m, as for a gold mine in the Kolar area at 3260 m depth. Russian metal mines will also enter depth levels between 2000 and 2500 m. As shown in Fig. 1,taking China as an example, in the next 10–15 years, 50% of iron ore resources, 33% of nonferrous metal resources, and 53%

Human Capital Considerations. Perhaps the greatest concern now facing the gold industry is the degree and rapidity of shrinkage in personnel. Chart 3 reveals that, over a twentyyear period since 1984, the number of unskilled personnel employed by the South African gold mining industry has fallen from 450,000 to 130,000 due to restructuring in the sector.
The current turbulence in the mining industry in South Africa has its roots in several different factors. First, the fall in global demand for platinum and other minerals due to recession; second, the consequences of the Marikana disaster in destabilising labour relations; and third, the structural character of our mining industry. A great deal has been
With more than 66% of all new mining exploration in the hardrock sector currently focused on gold, the problems are going to get worse for people and places around the planet. Project Underground
Advantages of Mining. Mining can help us to assure the supply of important resources. Important for our technological progress. Mining is necessary for many products of our daily life. Employment opportunities for many poor people on our planet. Can help poor regions to develop and to progress.

These findings were similar to our investigation in a deep gold mine in China and Joaquim's research, but different to Küller's findings. Univariate analyses suggested that the 3 most prevalent selfreported physical symptoms were related to worsened SCL90R subscales scores and multivariant analysis referred that the

Rock bursts accidents caused serious largescale damages to deep mine working faces, roadways, and contributed to a big number of casualties (Gibowicz and Kijko, 1994)The factors for rock burst in deep mines at Kolar Gold Field include the influence of geological discontinuities (faults and dykes), rock strata formation, physical and
Deep rock mining is a capitalintensive industry. Only a handful of people, eventually referred to as the Government involvement in the structure of work in the mines The gold mine owners faced three challenges to maximizing their profits: the gold deposits, although vast, Despite the challenges, black mineworkers organized themselves
The selfsustaining bacterial community, which thrives in nutrientrich groundwater found near a South African gold mine, has been isolated from the Earth's surface for several million years. It represents the first group of microbes known to depend exclusively on geologically produced hydrogen and sulfur compounds for nourishment.
Gold Mine Problem. Given a gold mine of n*m dimensions. Each field in this mine contains a positive integer which is the amount of gold in tons. Initially, the miner is in the first column but can be in any row. He can move only (right>,right up /,right down\) that is from a given cell, the miner can move to the cell diagonally up towards the

The planetGOLD programme, led by the United Nations Environment Programme (UNEP), aims to end the toxic trail of smallscale gold mining. Representatives work with governments, the private sector and mining communities across the world to eliminate mercury from artisanal mining and promote safer work environments.
The trend in underground mining is toward increased automation. Work is being done on developing robot machines with computer guidance even to the point of operating the machinery from the surface. Following is a copy of an article that has more detail about the Anglogold deep mining operations and plans. While Deepmine's
The Mponeng gold project is situated in the West Wits mining district, about 65km west of Johannesburg, South Africa. It lies near the town of Carletonville, on the border between Gauteng and North West provinces. The gold deposit sits on the northwestern rim of the Witwatersrand Basin. The main reef horizon mined at the Mponeng mine is the
