    Odpadowe muły węglowe jako element izolacji mineralnej składowisk odpadów

    Waste disposal is connected with hydro-ground environment contamination because of a toxic, chemical compounds migration. Agreement with existing regulations it is demanded of the storage yard protection by mineral insulation and synthetic insulation of the ground. Mineral fine-grained wastes are quite often offered to the mineral insulation building (for example: fly ash from commercial power engineering and clay rocks). It is possible using coaly sludge from coal enrichment process. The paper presents the possibilities of application of coaly sludge from KWK »Janina« (Libiąż) as an insulation material to the protection of hydro-ground environment in the storage yard region. Elementary parameters were defined: mineral composition, chemical composition and grain-size distribution. Additionally, physical properties were defined: density and volumetric density, optimum water content and maximum dry density. Variation of the hydraulic permeability with optimum porosity was correlated. It is possibility to use coaly sludge as the clay rocks substitute to the storage yard insulation.
