Definitions

  • the object of the present invention is the method of preventing infiltration of pollutants from mineral resource excavations to ground waters.
  • the Polish patent No. 376141 presented a method of sealing waste deposits which involves the creation of impermeable insulating layer of ash and cement with an in-built layer of vinyl-maleic copolymer, modified with carbonic acid diamide. Utilization of organic membrane, which degrades with time, as well as the use of cement, which doubles the cost of manufacturing the isolation, constitute disadvantages of this method.
  • the patent WO1997026416A1 presented the methods involving implementation of layered insulation, comprising a layer of plastic foil, layer of bentonite, loaded with a layer of soil on the top. In this case, plastic foil is also likely to degrade after some time.
  • the USA patent No. 5374139A presented the method involving the utilization of geotextile mat (0.6-0.2 pore size), covered with a layer of soil, on which waste glass and gelling agent is poured in order to lower water permeability.
  • geotextile matrix is also subject to biodegradation, which may result in leachates, years after the exploitation period.
  • the essence of the method of preventing infiltration of pollutants from mineral resource excavations to ground waters is that 50cm layer of coal gangue is 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.
  • the advantage of this invention is that it prevents infiltration of excavation pollutants to ground waters.
  • a 50 cm thick layer of coal gangue was formed, 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.
