The Institute for Mineral Resources Machine Technology (IMR) at the RWTH Aachen University, Aachen/Germany has been working on options to enable boundary layer detection as well as horizon control for underground coal operations for more than a decade. One of these tested options is laser-induced breakdown spectroscopy (LIBS). After a short introduction into the technology of LIBS, this article describes ...

Freiberg Mining Academy was established in November 1765 by Prince Xaver, regent of Saxony, based on plans drawn up by Friedrich Wilhelm von Oppel and Friedrich Anton von Heynitz. It was set up as a training institution for mine engineers and was known as the Electoral Saxon Mining Academy of Freiberg. Teaching began in May 1766. The new institution was ...

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 ...
