In the harsh conditions of raw materials extraction underground, people and machines alike are pushed to their absolute limits. Every single component matters. If just one of the “cogs” fails in a mining operation, the cost of repair and reinstatement is many times that in other branches of industry or production. One of those cogs is the cable required for ...

The market for machines and equipment in underground mining will experience significant growth in the coming years. Siemens AG in Nuremberg/Germany has spent years cultivating long-term and successful business relationships with a number of major vehicle manufacturers in the field of mobile mining technology. These relationships are the foundation for expansion of the company´s portfolio to include diesel-electrical drive systems ...

The influence of underground openings due to mining activities on ground subsidence and sinkholes can be minimized by the use of backfill material. Mechanical properties of the backfill material, e. g. material stiffness, are depending on the pressure, and if binders are used, are also developing with time. Numerical simulations are an efficient tool to help estimating the influence of the ...

China, the world’s largest coal market, is also showing signs of increasing sensitivity in the face of environmental and social issues. The Chinese Government has reacted to this and the coal industry – which admittedly is also suffering from over-capacity and a high level of debt – has as a result been obliged to adopt with a wide range of ...

World coal consumption and production declined through 2016, though there were significant regional differences. The global downturn in consumption was mainly a result of significant reductions in China and the USA. While in Europe coal has been in retreat for many years, it has been making further gains in parts of Asia, and especially in India and in the south-east. ...

For social security organizations prevention historically has played a key role. Besides compensation and rehabilitation, prevention was part of the provisions of the first social security scheme established in 1884 in Germany by Chancellor Otto von Bismarck and prevention efforts have increased dramatically with the industrialization of our societies. In the 20th century, the main focus in prevention was on ...

This paper builds the bridge in mining developments from the 1980s to the presence and to what will happen in the future. It not only includes technical developments but especially social ones. The article is the conclusion of the author´s presentation, given at the “Forum Bergbau 4.0” conference of the RWTH Aachen University on 1st December 2015. Where do we ...

Today, it seems like everyone is talking about Industry 4.0 concept. However, only a few know what really is behind it: The Federal Government has set a goal to advance Germany with its high-tech strategy towards becoming a global innovation leader. The concept of Industry 4.0 is one of ten future projects that makes a featuring part of this “new ...

Digital technology, digital transformation or digital economy are currently big buzzwords as we have seen many industries disrupted by new sales channels, digitized products, new business models or market players. What started with digital music at the turn of the century is now finding its way into more and more industries. Even the mining industry is increasingly looking at how ...
