1 Until the End and beyond: Elements of a Sustainable Development Strategy for the Mining Industry Prof. Dr. Jürgen Kretschmann President Technische Hochschule Georg Agricola University, Bochum, Germany, 1

2 Content Past Coal Mining in Germany Present Sustainability and Post-Mining Future Post-Mining Education The Basis for Post- Mining Excellence 2

3 Coal Mining in Germany GVST Past 3

4 The Ruhr Area in the Centre of Europe Inhabitants: 5.2 Mio. surface area: sqkm GDP (regional): 144 billion Euros Home of many large German companies Home of RAG, the sole German Past Stadtarchiv Bochum/ Slg. Chr. Dahm hard coal producer 4

5 Abandoned Mine Sites in NRW Areas in NRW affected by abandoned mine sites 5

6 The Ruhr Myth Industrial heart of Germany since the 1850ies The Kohlenpott (Coal pot) with more than 300 coal mines was the economic power house of Germany. Image: hard labour, bad living conditions Past 6

7 Hard Coal from the Ruhr: Nothing is for Eternity introduction growth stagnation decline Turnover Coal mining was the basis of Germany s economic miracle after World War II. Time but Mio/t Past Source: Statistik der Kohlenwirtschaft e.v Production of hard coal began to decline in the 1960ies. The lifecycle will end in

8 Hard Coal from the Ruhr: The region must go on Unemployed Ruhr area Miners Ruhr area Source: Bundesagentur für Arbeit, NRW; RVR-Datenbank-Statistik; Statistik der Kohlenwirtschaft e.v The miners workforce diminished in the course of the decline but The structural change in the Ruhr area constantly creates new opportunities for the citizens Population Ruhr area Working population Ruhr area Source: Landesbetrieb für Information und Technik, NRW; Statistisches Bundesamt Wiesbaden. Past 8

9 Sustainability and Post-Mining In 2007 the German government has passed a law on funding the termination of hard-coal mining. the RAG-Stiftung (RAGfoundation); RAG subsidized coal mining unit plus coal trade, land management, site development; Evonik Industries one of the world s leading specialty chemicals companies Past 9

10 The RAG-Foundation ensures that the RAG Corporation can discontinue subsidized coal mining in a socially acceptable manner by the end of in 2019, the RAG-Foundation will finance RAG s perpetual mine management obligations related to coal mining. The foundation will finance these obligations through the sale of shares in Evonik Industries AG, through the income from its holdings, and through the income from its diversified financial assets. The RAG-Stiftung also aims to promote the Ruhr and Saar regions by supporting educational, scientific, and cultural measures related to coal mining. 10

11 Sustainability and Post- Mining: the RAG strategy environmental damages caused by coal production should be limited and handled carefully (environmental dimension), the costs of managing the postmining tasks should be managed efficiently (economic dimension), the population in the mining regions should be offered good future prospects to ensure their standard of living and their well-being after mining has come to an end (social dimension). Present 11

17 Analysis of Post-Mining Challenges Challenges underground Present 17

18 Perpetual challenges of the hard coal mining Mine dewatering Polder measurements Calculated costs about 220 million p. a. from 2019 Groundwater purification Groundwater purification Polder measurements Mine dewatering Present 18

19 Handling of Mine water Mine water drainage is the biggest and most expensive challenge among the perpetual tasks. RAG pumps 70 million cubic meters of mine water per year water drainage is important to avoid groundwater contamination by mine water, Mine water endanger the drinking water supply in the regions Present 19

20 Evaluation of ascent processes of mine water Present 20

21 Monitoring the mine water underground Modified deep-see CTD 75 M probe for underground mine water monitoring Monitoring of the mine water uplift process in mine excavations Measurements of water pressure, temperature, mine water current and permeability With the aim to sharpen the comprehension of the process of the mine water ascent Present 21

22 Monitoring the surface Aim: development of a monitoring concept for the whole Ruhr Area Use of a satellite based monitoring in postmining areas Technology: European earth monitoring program Copernicus based on the use of Sentinel-satellites (launched ) Application of satellite data for remote sensing and monitoring of concrete postmining processes on the surface Present the Sentinel satellites are capable to monitor even small deformations in Earth s surface 22

26 Benefits of Post-Mining for all stakeholders: Citizens / society Improved living environment and perspectives Higher identification with the region Positive impact on the labor market (new jobs) Profits and cost reduction Municipalities / Politics Tax receipts from new businesses Signs for a positive structural change New business clusters Improving the image of the communities City gains positive reputation and scientific attention Business and science Development of future orientated projects in practice Creating new R&D networks Direct access to future energies Development edge Mining Company Financial benefits from new businesses New contacts, networks and partners Better marketing opportunities Better image Present 26
