Wind power is one of the politically prioritised options for the energy transition to climate neutrality at coal sites, although the use of “Carbon Capture and Storage” (CCS) technology during coal-burning operations is also a possible method for the reduction of CO2 emissions. Wind power is undergoing impressive technological and economic development, and its expansion enjoys a high priority in energy ...

Politics, specialist science and the mining supply industry are equally bound to tradition and committed to the future. All stakeholders are now committed to the energy transition. The state government in North Rhine-Westphalia is pursuing the goal of climate-neutral electricity generation by 2050. To this end, renewable energies are to be expanded and further advanced. In their coalition agreement, the ...

The issue of methane (CH4) has been on the European Union’s agenda for a long time and is now being pushed in order to achieve the goal of net zero greenhouse gas emissions in the EU by 2050, on the one hand overzealously, but also with little knowledge about the origin and source of methane emissions in active and abandoned ...

Mine gas from abandoned mines is a special topic of European and national climate policy. It continues to threaten to escape from coal deposits that have not yet been affected by flooding. The initial support for the utilisation of mine gas for electricity generation via the Renewable Energy Sources Act (EEG), which expires for most mine gas plants by the ...

In order to keep the mine workings in the German coal mining industry dry, the mine water had to be lifted from great depths and brought to the surface for centuries. With the phase out of hard coal mining in the Ruhr area and in Ibbenbüren in 2018, the original purpose of this mine water management was lost. Since then, ...

From municipal landfills, methane-containing landfill gas is produced during the conversion of biogenic organic matter, which has a very high greenhouse gas potential – more than 28 times stronger than carbon dioxide (CO2) over 100 years. Based on decades of experience, it is extremely difficult to adequately capture this landfill gas in a heterogeneous heap (landfill body) – due, among ...

The abatement of greenhouse gas emissions has long been a focal point of international climate policy as an important aspect in achieving or as the direct topic of climate targets. As a greenhouse gas with a relatively short life time in the atmosphere and strong global warming potential compared to carbon dioxide, methane emission abatement measures present an opportunity for ...

In mining and remote areas of resource industry, there has been a development towards lacking emergency medical first aid response, that creates a potential disadvantage for patients after work accidents and other medical emergencies compared to standard population. This is due to structural changes in mine rescue brigade coverage caused by transformation from formerly few major resource companies towards many ...

The shutdown of hard coal production in 2018 implicates a challenge in deriving of physical and chemical parameters of mine water in situ. Finishing underground activities is going along with a limitation of alternative application of monitoring methods. This report is focussing on measures to derive sufficient information about water rebound in former mines. Exemplarily results of an underground monitoring ...

The year 2020 marked the start of an integrated process aimed at monitoring rising mine water levels in the former hard coal mining industry of the Ruhr coalfield and the Ibbenbüren coalfield. This paper presents the different topics that are to be dealt with and the assessment strategy that has been laid down for the monitoring operation and also examines ...
