What is the German Mining Network? The German Mining Network is a platform of mining and raw materials experts that comprises the German Mineral Resources Agency (DERA) in the Federal Institute for Geosciences and Raw Materials (BGR), Germany Trade and Invest (GTAI) and six international competence centres affiliated to each of the bilateral Chambers of Commerce (AHK) in Australia, Brazil, ...

The coal deposits of the gassy Zollverein 1/2 seam at Prosper-Haniel colliery were developed from the Prosper Nord working district on mine level 7 (1,159 m below sea level). This comprised the three coal panels numbered 123, 121 and 124. Preliminary gas drainage was a key factor leading to the success of the panel extraction projects in Zollverein 1/2 seam. ...

Increasing lengths of longwalls, increasing support forces of shields leading to higher hydraulic pressure, bigger cylinder diameters in the roof support as well as increasing speed of extraction machines place high demands on the hydraulic supply. Modern hydraulic stations for high production longwalls provide reliably and at high availability more than 2,000 l/min emulsion at a system pressure of 350 ...

The German coal industry has been using two-component resin injection as a strata reinforcement and consolidation technique for more than 30 years. Up until the early 1990s these products were mainly processed and delivered via simple pneumatic and hydraulic piston pumps, with pneumatically driven geared pumps also being employed in some cases. The resin products were supplied in disposable cans ...

The implementation of new technology into an existing mining operation can deliver a step change in operation and commercial benefits. But it also comes along with risk. Integrating new technologies is connected to a number of challenges that could result in the rejection of the innovative technology. Detailed planning, robust project management, a good customer relationship and an evaluation of ...

Saving energy in industrial processes and also in mining underground processes is crucial for modern production. The dependency of different solutions not only on the energy consumption but also on the productivity and the process outcome has to be concerned. For this reason, the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), Stuttgart/Germany, developed a simulation based model which simulates ...

The Québec Government is currently working to introduce a stimulating and advantageous investment framework for the mining sector. The aim of the new Plan Nord, launched in the spring of 2015, is to develop mining, forestry, energy, social, cultural and tourist potential in the area of Québec located north of the 49th parallel, and to create jobs and wealth for ...

The Chinese economy has continued its downward trend in 2016. Poor sales prospects have resulted in no more than a moderate increase in investment in most sectors. As a result, the mining industry is not expected to make much of a headway this year and for those German supplier companies that have manufacturing bases in China efficiency improvement has now ...

The Kazakh mining sector is gearing up for long-term expansion in the years ahead. The country remains a major supplier of raw materials to the Asian and European markets and while the price of coal, copper and iron ore could well remain weak up to 2020 this sector is still well placed to meet the future. Though Germany and Kazakhstan ...

The worldwide mining industry is currently facing a significant restructuring process. In most underground mines, widespread mechanization of the mining processes increases production while reducing staff numbers. At the same time, the mining depths as well as the lateral spread of the mine workings are increasing. This ever changing mining environment is requiring sophisticated solutions for the design and operation ...
