Mining in the Heat
Effective lubrication can help mining operators achieve greater efficiency and lower running costs. But in the sector’s notoriously tough, hot conditions, there are several environmental challenges to consider and overcome when choosing and administering a grease. From equipment variations, to high loads, searing temperatures and possible contamination, there is a…

The Use of Numerical Simulations in Longwall Coal Mining
Numerical simulations provide a cost-effective way to plan and optimize a longwall. In this study numerical simulations are used to identify the necessary support pressure and the maximum distance between shield support and coal face in a target coal seam. The stress state, as well as the subsidence and the…

How Seemingly Normal Operating Conditions can Lead to Accidents
The control of process systems is usually based on the measurement of process variables such as temperature, pressure, quantity or level or certain material properties. The processing of the information determined by sensors in the process control system, the display of the data in the control room or at the…

Thermal Energy Transition with Geothermal Energy: From Coal Mining to Heat Mining
The coal phase-out in Germany by 2038 constitutes a major challenge for regions and industries. Technologies, energy sources and labor markets are changing fundamentally. But there are also opportunities for local actors that are worth to be explored. Even old mines could contribute to the success of the transition of…

GeoLaB – The Geoscientific Future Project for Germany
Geothermal energy can play an important role in the decarbonization of the German energy system. In order to make the great potential of geothermal energy in the crystalline basement economically viable, measures are taken to enhance existing permeable structures. However, a prerequisite for the public acceptance of such Enhanced Geothermal…

Renewable Geothermal Energy – Latest Developments in Geothermics in North Rhine-Westphalia: New Finds. New Projects. New Research Facilities.
Geothermal resources have huge future potential and could well replace much of our fossil-fuel and nuclear based heat and electricity supplies. Geothermal energy is climate neutral and is available all year round. However, it presents significant technological challenges and is highly capital intensive. This applies both to near-surface geothermics and,…

Geothermal Energy Utilisation in Austria
By late 2020 a total of 77 deep geothermal wells had been drilled within the territory of Austria, representing a cumulative length of some 135 km. About two thirds of this figure, both in terms of number and cumulative length, comprised boreholes sunk in sedimentary basins, while the remainder were…

The Impact of Geothermal Energy on Natural Gas Production
Natural gas is besides from crude oil and coal one of the most important energy resources. However, during the depletion of a reservoir, the occurrence of liquids, e. g., water, condensates, is a well known phenomenon worldwide. Depending on the gas composition and the physical boundary conditions (pressure, temperature), water and/or…
