A river runs through it: Displacement of Serbia's Kolubara
The Kolubara Open Pit Coal Mine is a critical supplier of lignite coal for the production of electrical energy in Serbia and Montenegro and supplies more than 85 % of that demand. To continue the current production of more than 26 million tons of coal per year, the mine within the coal basin had to be expanded from the eastern region to the western region. In order for the first phase to be accomplished in 2007, the Kolubara River and its tributaries had to be redirected for more than 5 km. It was determined that the new river channel must be designed with an impervious lining system to prevent infiltration of river water into the open pit mines and to prevent a potentially catastrophic collapse of the river channel during high flow or flood conditions. In addition to the use of a CCL over stable excavation areas, it was determined that a combination of CCL and highly extensible geomembrane would be required in areas that would be subjected to differential settlement. The 1.0 mm-thick EPDM geomembrane was protected placing 350 g/sm nonwoven geotextiles top and bottom of the geomembrane system. A detailed QAS was specified and implemented to ensure quality of the critical lining system from manufacture through protective cover soils and aggregate placement. The additional requirements for large and custom-made panels and rapid deployment during staged construction of the new river channel was also critical. Timely planning and implementation for the mine's largest expansion and redirecting a major river was crucial, and the use of a geomembrane system was instrumental in achieving this goal.
