  1. 2nd International Conference GrazOctober, 10th 2012 Effects on Groundwaterby Mining Adaptation Topic 1 PP8 – LfULG (speaker: Corina Niemand) PP7 – IRRI PP2 – RWM (PP6 – IMGW)

  2. Future topics Legal execution Support ofpolicy Research Education Transfer ofknowledge andtechnology Financial support Environmental monitoring LfULG - Areas of Work

  3. PP Mining Areas - Active Mining Active Ayrshire, Scotland Jänschwalde, Germany • Where is know how existing ? • Where will be the benefit? www.kier.co.uk fotocommunity.de :Hardy Ulitzka mining Ptolemaida, Greece Turow, Poland http://img.fotocommunity.com/photos/12070483.jpg

  4. Poland (turow, Gwra) After Mining Greece Radke, Peter (LMBV)

  5. In which respect is it relevant to the donor partner(s)? But: Way islong and difficult! http://moorbraun.twoday.net/stories/5055934 Quantity Problems Quality • poor water quality of ground and surface waters • low pH values – acidminedrainage • high sulfate concentrations • high concentrations of dissolved iron • containing a high level of suspended solids • andothers • (Enormous) groundwaterdeficit • Lusatian mining area 1990: around 13 billion m³GW deficit groundwaterloweringfunnelsabout 2100 km2

  6. What is the role of the receiving partner(s) in the adaption process? Adaptation Process: Where were obstacles in the transfer of the selected methodology ? More time Table

  7. Groundwater– Quantity mining Beforemining After mining filled floodedbygroundwaterandsurfacewater

  8. Acidminedrainage

  9. What can be done? 1. Quantity 2. Quality ActiveMining Beforemining mining Mine watertreatmentplants

  10. Characteristics of the good practices What can be done? Oxidative mine water treatment

  11. Characteristics of the good practices Example: Mining Area Schleenhain, Germany

  12. What can be done? After mining filled floodedbygroundwaterandsurfacewater 1. Quantity http://dabonline.de/wp-content/uploads/lmbv_1042-201x300.jpg http://www.kuehn-hjp.de/Meuro/e3-44-10b.jpg

  13. 2. Quality What can be done? In lake In Situ On site Stationary entry above and below the water surface Mobile entry above and below the water surface Improve sustainability by buffering with CO2 and power plant ash Microbial sulfate reduction by DSI Sulfate reduction with fixed-bed reactor Reduction of groundwater recharge Mine water treatment plants Microbial ammonium reduction Electrochemical reduction of sulfate Seewasser runoff water dumpandgroundwater seawater

  14. Characteristics of the good practices What can be done? Inlake method to neutralize the lake water

  15. Characteristics of the good practices Inlake - Technologies Use of remediation ships: alkaline buffering by entry of HCO3 generated on board in the surface water body (Inlake liming) reference LMBV

  16. What exact steps were needed for a potentially successful transfer? What should be done? Basic research Applied research (laboratory / pilot plant test) • passive / activetechniques • geotechnical, chemical, physical, biological, microbialprocesses Pilot test at the site Use in rehabilitation

  17. What should be done? Rehabilitation technologies – stateofresearch Substrate Infiltration well well Substrate concentratetdgroundwaterflow moraineclay

  18. The end of the project SHARP is not the end of cooperation • „…Fillingoldmineswithwater must be…“ SHARP-Song Vers 3 • Enormouswaterdeficit •  needtoknowthewaterbalance in theregion • Project of PP7 and PP8 • 2012-2014 TransboundarycatchmentareaLusatianNeisse
