Renewable power options are fairly new to the mining sector and are now just at the beginning of the scaling stage. However, they have gained a lot of momentum in recent years and an increasing number of projects are being realized across the globe and in various climate zones. Nonetheless, the largest share of the overall potential is still untapped ...

ENERCON GmbH, Aurich/Germany, is a privately-owned manufacturer, constructor and operator of high-performance wind turbines. The company is built on values such as innovation, quality and entrepreneurship; all of which help achieve the goal of providing renewable energy to the world – wherever the need for energy may be. With this vision in mind, ENERCON accepts the challenge of building windfarms ...

In many countries, the cost of solar power is already at about the same level as the cost of power from coal-fired power stations. Especially in comparison with existing diesel power stations, solar power has been able to develop its cost advantages to the full as a result of the continuous fall in system costs. As a decentralized source of ...

Electricity generated from photovoltaic (PV) systems can mean a great deal to mining industries who either have limited or no grid access at all. For companies that rely on a diesel power supply, a PV plant can reduce fuel consumption and thus operating expenditures dramatically. Grid connected facilities could also profit from an additional renewable power supply as it provides ...

The mining sector represents the largest source of revenues and the most important sector of Chile´s economy. At the same time the Chilean mining sector is the largest of the country’s industrial energy consumers. The share of energy costs in the total operating costs of Chilean mining operations is between 20 and 40 % and therefore represents a significant factor influencing ...

This year’s Annual Report of the German Coal Association (GVSt), Herne/Germany, is entitled “Still dependable in a changing world”. This reflects not only the fact that all the industry’s agreements and commitments are being kept but also that reliability is the defining theme for the end of the coal mining industry in general and for the future tasks that will ...

Fires have been one of the major hazards for miners. In order to minimize fire risks in underground mines, preventive measures need to be taken. Such means are for example using materials which are hard to ignite and hardly spread fire or hydraulic fluids with low flammability. Testing and assessing those properties is standardized in Germany and Europe. In addition, ...

Since the mid sixties, there were over 200 spontaneous combustion fires in German collieries, with more than a dozen cases of CH4 ignitions. It should be agreeable that the related mine rescue work for the prevention of damage to property should not be more hazardous than ordinary underground work. This claim requires a regular check of safety regulations for the ...

The arising of smouldering fire of slack coal in close proximity of conveyer belt systems still cannot be prevented despite of all safety engineering. That is why it is necessary to find the source of fire at an elementary stage and detect it locally. The GESO Firefinder M is based on the technology of fibre optical distributed temperature sensing and guarantees ...

By adding a special foam concentrate and compressed air to water the One Seven MINING system produces compressed air foam (CAF). The foaming agent is a surfactant and a non-flammable substance unlike phenol or polyurethane. By inundating a mine space with foam it displaces any explosive gases and prevents oxygen contact with the fuel. The foam has strong penetrating and ...
