Abstract (en)
A method of preventing infiltration of excavation pollutants to ground waters characterized by a 50 cm thick layer of coal gangue, sprinkled with 10% suspension of ash, which was obtained through bituminous coal combustion, or preferably - brown coal - 5 times over 10 days, in the amount of 0.3 m 3 of suspension per 1 m 2 of created surface, which is compacted with a road roller after 50 days and then covered with at least 50cm thick layer of coal gangue. The excavation is then filled with coal gangue up to 2m below the planned surface level, while the upper 2-meter thick later is filled with a mixture of soil from landfill cover and post-fermenting sludge from agricultural biogas plant in the weight ratio of 9:1.
