W ostatnich latach w górnictwie podziemnym szeroko stosowane są technologie górnicze, wykorzystujące na dużą skalę drobnofrakcyjne odpady energetyczne, a w szczególności popioły lotne. Znaczna ilość zakładów energetycznych oraz kilka istniejących metod odsiarczania powodują, że powstające masowo popioły lotne różnią się pod względem składu chemicznego oraz własności pucolanowych. Dlatego dla optymalnego wykorzystania popiołów lotnych w technologiach podziemnych niezbędne jest przeprowadzenie badań, w celu poznania ich własności. W artykule przedstawiono wyniki badań hydromieszanin, sporządzonych na bazie popiołów lotnych z kotłów fluidalnych trzech wybranych zakładów energetycznych. Na podstawie tych badań dokonano oceny przydatności tych hydromieszanin dla obecnie stosowanych technologii górniczych.

In the last years in polish underground mining we can see intereasing of use energeticwaste (fine-gresnded waste) in particular fly ashes. The paper presents results of laboratory tests with use of ashes made with fluid-boilers (three chosen power plants). On the basis of this evalution of useful for this fly ash-water slurries in underground technologies was made.

In the Upper Silesia Coal Basin and on the adjoining areas, besides dominant in resources and the amount of bituminous coal output, there of other occurs mineral raw materials. In spite of local industry restructuring, production of mineral raw materials in this region still remains significant for its economy. Among other European Community countries the larg-est bituminous coal resources occur in the Upper Silesian Coal Basin. Poland is the European Union leader in coal production and export. Exploitation of some mineral raw materials, such as: iron ores, zinc-lead ores and brown coal, in different times was discontinued while others (rock salt, Mo-W-Cu ore) from beds recognized to a different degree was not started. Making use of waste mineral raw materials, mainly mining, metallurgical and energetic ones, is becoming more and more significant economically and ecologically. Sometimes synthetic raw materials are produced, such as: gypsum (desulphogypsum) obtained from desulphurisation of fumes, Ca-Mg fertilizers from dolomite wastes, crushed and synthetic aggregates from mining and metallurgical wastes, lead and silver from recycling and salt from coalmine water desalination. On the basis of imported raw minerals, iron, steel and ferroalloys are produced. Zn-Pb concentrates are also imported on larger scale. Such raw materials as: raw materials used for production of noble ceramics and rock wool are delivered from other regions of the country. Sustainable development of the Upper Silesia leads to rational and environment friendly managing of mineral raw materials, protection of their resources, as well as to usage of industrial wastes. Protection of resources from neglected deposits (coalmines in liquida-tion) constitutes an important problem, still to be solved. It is connected with substantial financial spendings and preparation of suitable legal acts. A substantial amount of mining, processing, metallurgical and energetic wastes, accumulated as well as produced on a regular basis, requires suitable management. An appropriate example of that is placing mining and energetic wastes under the ground, using them as consolidating stowing for sealing cavings and using them as a dummy road packing. Mining wastes are also applied in engineering works, such as for instance, in construction of embankments, land levelling etc. Flotation silt is used as fuel in the households and the material obtained after their decarbonisation is used in recultivation.
