Innovative Hydraulic Roof Support for Low Seams
One of the basic problems of Polish underground mining is low seams extraction. The main impediment in this case are extremely harsh exploitation and operation conditions of long-wall complex machines, which in most cases result from mining conditions and the characteristics of powered hydraulic roof supports. According to this, in…

Cabling for Energy and Control Technology in Deep Mining
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…

Simulation of Pressure- and Time-Dependent Behavior of Backfill Material in Numerical Calculations
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…

Coal Market 2016
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…

The ISSA Vision: Promoting Safety, Health and Wellbeing in a Changing World of Work
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…
