The Cost Savings Potential of Solar Power and Battery Storage for Mining Companies, Taking the Example of the DeGrussa Solar-Diesel Hybrid Off-Grid Project in Australia
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…

Sun Instead of Diesel: The Largest PV Diesel Hybrid System in South Africa Supplies a Chrome Ore Mine
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…

Fire Prevention in Underground Mining – Requirements for Equipment in Germany and Europe
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…

Hazard Analysis on Underground Mine Fires in Collieries
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…

Early Detection of Smouldering Fire Using the GESO-FireFinder M-System – Description and Experiences
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…

One Seven MINING – an Innovative System for Firefighting and Prevention in Mining
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…
