Future since 1816: Celebrating 200 Years University of Applied Sciences TFH Georg Agricola
On 15 April 2016 the University of Applied Sciences TFH Georg Agricola is celebrating its bicentennial of existence. On this very day in 1816 the first fourteen students commenced their studies at what was then the Bochum Mining School from which, after quite a few transformations, TFH Georg Agricola eventually…

Developments of the International Mineral Markets Considering the Chances of German Mining and Conveying Technology
Following-up with recent press news it becomes obvious that the international mining industry is in deep crisis latest since 2014. This was initiated by lesser demand from China which in-turn is well known for setting records over the past but calmed down their mineral consumption and own mining activities as…

Underground Loading and Transport Systems and the Challenges Posed by Increased Production Levels at Ore Mines around the World
Developments in production levels at ore mines as a result of the transition from large opencast mines to deep mining have forced mine operators and machinery manufacturers towards greater modernisation and innovation, especially when it comes to methods and technology for ore loading and transport. Large-scale opencast mines producing copper…

Assessing the Corrosion Risk to Coal-Face Chains
Coal winning is now generally associated with the mechanised longwall face system. Data on the actual number of such production units is currently only available for a few countries, though recent estimates have suggested that there are about 2,000 longwall faces in operation at collieries around the world, with about…

Using a Hierarchical Approach for the Dilution of Gases
In order to ensure safe underground working conditions, especially in case of gas outbursts, it is essential to develop ventilation concepts for the necessary dilution of harmful gases with respect to the occurring gases, gas concentrations and general operational conditions as to cross-sectional areas and existing ventilation systems. Therefore, a…

Optimizing Long-term Mine Water Management of Mining Sites with the Help of Directional Drilling and Liner Technology
The exploitation of raw materials in opencast or subsurface mining is usually followed by an impact on the water balance. To guarantee a secure and efficient production process the water must be drained. The environment-friendly mine water management should be implemented during the active mining as well as in the…

About Possibilities to Improve Current Outburst Hazard Prediction Based on Updated Mechanism of Coal and Gas Outburst
In this paper the problem of coal and gas outburst – the coal pit’s most complex and dangerous induced geodynamic phenomenon – occurrence and development has been considered in details. Based on the theoretical and experimental researches it has been shown that this phenomenon may occur in full strength only with…
