When a mine is in operation the main concern \u2013 for both underground and opencast workings \u2013 is to ensure that the mining area is kept free of water in order to create a safe and properly functioning environment. These dewatering operations are mainly in the interest of the mine operators. However this situation changes when the production phase ceases and there is growing public interest in what is to happen with the former mining site. The issues that arise in this context mainly have to do with the impact of mine water on the groundwater bodies, the flooding of residual opencast mining cavities, the restoration of residual lakes and, essentially, the treatment of mine water with a view to preventing pollution and contamination.<br \/>\n<a href=\"http:\/\/2025.mining-report.de\/english\/current-issue-3-2019\/\" class=\"shortc-button small white\">Read more<\/a>\n<p>With my best regards \/\/ Mit freundlichem Gl\u00fcckauf<br \/>\nDipl.-Ing.

Therefore new options arise to redesign the mine water management in the post-mining future. The mine water conception of RAG Aktiengesellschaft, Essen\/Germany, includes a reduction of the number of dewatering stations, their conversion into well-operated pumping stations and the rebound of the mine water level. Especially with regard to the discharge into streams there is the chance to keep numerous rivers and their tributaries free of mine water. In the Ruhr coalfield, only six out of currently ten dewatering stations are supposed to stay in operation.<\/p>\n<p><strong>Authors:\u00a0<\/strong>Isabelle Balzer M. Sc., Dipl.-Geol.

In order to fulfil the purpose of eternity of the mine water draining and to reduce operating costs in the long term, the rising mine water is to be captured safely at a defined level and permanently fed to a water treatment system by gravity. In order to fulfil this task a new about 7.3 km long mine water sewer has been projected.

Switching off the pumps generally results in an increase in mine-water levels. This process can take place very quickly or may even last several years or decades. Rising mine-water levels are an ongoing event in many places, not only in Germany but around the world, and the public is sometimes completely unaware that they are happening. In the former mining area of South Butterknowle in the Durham coalfield (United Kingdom) an inaccurate assessment of the hydrogeological conditions resulted in mine water and groundwater being mixed together. This paper will seek to show how lessons can be drawn from the Durham experience and how the mine-water management procedures adopted during the post-mining phase in the East of Wear (UK) and Lorraine (France) mining areas can be adapted with a view to providing long-term protection for the aquifers in these regions.<\/p>\n<p><strong>Authors:\u00a0<\/strong>Dr. rer. nat.

The situation in the residual lakes, where geotechnically prescribed water limits were reached in the Lausitz area, was successfully kept under control by means of an active management regime. The only incident occurred at the Senftenberg public lake where the low water levels caused some slippage on the island. During 2018 work in the Lausitz area continued to focus on developing a hydrological regime that would be as self-regulating as possible.

Among various direct and indirect power storage technologies, pumped hydro storage power plants are known as the only proven large-scale storage technology for more than a century. Pumped hydro storage power plants have many advantages: They have a long service life, can store energy over several hours or days, and have relatively low specific costs compared to other storage technologies. Nonetheless, pumped hydro storage power plants use large areas of land and people are often hostile to new projects. A solution to these problems are underground pumped hydro power plants.<\/p>\n<p><strong>Authors:\u00a0<\/strong>Dr. Maik G\u00fcnther und Dr. Christoph Rapp, Stadtwerke M\u00fcnchen GmbH, M\u00fcnchen, Mostafa Fallahnejad M.Sc., Technische Universit\u00e4t Wien\/\u00d6sterreich<\/p>\n<a href=\"https:\/\/2025.mining-report.de\/english\/why-underground-pumped-hydro-storage-plants-despite-their-broad-advantages-are-not-built\" class=\"shortc-button small white\">Read more<\/a>\n\n\t\t<div class=\"clearfix\"><\/div>\n\t\t<hr style=\"margin-top:10px; margin-bottom:10px;\" class=\"divider divider-normal\">\n\t\n<h3>Making Homes where Collieries once stood<\/h3>\n\n\t\t<div class=\"clearfix\"><\/div>\n\t\t<hr style=\"margin-top:10px; margin-bottom:10px;\" class=\"divider divider-normal\">\n\t\n<figure id=\"attachment_8595\" aria-describedby=\"caption-attachment-8595\" style=\"width: 1500px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/2025.mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2019\/06\/RAG_MI_04_Gei\u00dfwies-Saarland_Thomas_Stachelhaus.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-8595\" src=\"https:\/\/2025.mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2019\/06\/RAG_MI_04_Gei\u00dfwies-Saarland_Thomas_Stachelhaus.jpg\" alt=\"\" width=\"1500\" height=\"519\" srcset=\"https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2019\/06\/RAG_MI_04_Gei\u00dfwies-Saarland_Thomas_Stachelhaus.jpg 1500w, https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2019\/06\/RAG_MI_04_Gei\u00dfwies-Saarland_Thomas_Stachelhaus-300x104.jpg 300w, https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2019\/06\/RAG_MI_04_Gei\u00dfwies-Saarland_Thomas_Stachelhaus-768x266.jpg 768w, https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2019\/06\/RAG_MI_04_Gei\u00dfwies-Saarland_Thomas_Stachelhaus-1024x354.jpg 1024w, https:\/\/mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2019\/06\/RAG_MI_04_Gei\u00dfwies-Saarland_Thomas_Stachelhaus-600x208.jpg 600w\" sizes=\"auto, (max-width: 1500px) 100vw, 1500px\" \/><\/a><figcaption id=\"caption-attachment-8595\" class=\"wp-caption-text\">Fig. 4.

And the active mining industry, in the shape of the current Lausitz Energie Bergbau AG (LEAG), Cottbus\/Germany, has played a key part in this work. The company\u2019s remit is to extract and process the indigenous resource and to ensure rehabilitation and recultivation of the landscape after mining operations have ceased. In the course of the last two decades the LEAG has restored nearly 6,900 ha to arable use. Any attempt at compensating for an industrial incursion into the natural environment must ensure that the affected land is restored in as effective a way as possible \u2013 which means shaping a sustainable, economically viable and secure post-mining environment.<\/p>\n<p><strong>Author:\u00a0<\/strong>Dipl.-Ing.
