Post Mining

Trust is a valuable asset that must be built and maintained in scientific and technical projects. Especially in projects of the mining life cycle, which are due to the change of the social perception towards a circular value chain, trust is under special observation and has to be built up actively. The difficulties here lie in the transfer of the ...

After the end of lignite mining in the Rhenish mining area, the remaining volume of the three existing opencast mines will be filled with water. The creation of opencast mining lakes on a scale that has not yet been achieved anywhere in the world represents a complex task for the mining company and the responsible authorities. The authorisation and supervisory ...

During the expansion of the Ehestorfer Heuweg road in the village of Ehestorf, district of Rosengarten/Germany, a daybreak occurred on 11th September 2019, which had a diameter of approximately 0.5 m and a depth of approximately 5 m. Research in the archives of the State Office for Mining, Energy and Geology (LBEG) in Clausthal-Zellerfeld revealed that the probable cause of ...

Even before the Act on the Financing of the Phase Out of Subsidised Hard Coal Mining came into force at the end of 2018, the effects of mine flooding on mining damage were increasingly becoming the focus of public attention. In order to pool knowledge on the possible effects of mine flooding on the surface in advance, the working group ...

In the Rhenish mining area, RWE Power AG operates the three opencast lignite mines Inden, Hambach and Garzweiler. According to the original plans before 2016, the Hambach and Garzweiler opencast mines were scheduled to run until 2045, the Inden opencast mine until 2030. In the context of the energy turnaround, the opencast mine plans and lifetimes have been adjusted several ...

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 ...

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 ...

There is an old saying that “mining is not a one-man operation”. This is borne out by the ongoing dialogue that is needed across the disciplines to manage the environmental issues associated with the mining life cycle at a local and wider level. Given the global nature of the mining industry we now need to develop a productive outcome by ...

Ukraine ranks 7th place in the world in terms of coal reserves. On the territory of Ukraine there are three coal basins: Donetsk, Lviv-Volyn and Dnipro, the largest of which is the Donetsk basin, where 85 % of Ukraine’s coal resources are concentrated. Since the mid of the 1990s the coal industry of Ukraine is being restructured, the purpose of which ...
