    Liquidation of mining workings, particularly mine shafts represent a complex subject, especially in case of water and gas hazard presence. This paper relates to results of research obtained from many years of experiences collected by the team of researchers on the use of highly densified mixtures (composite materials) made from power generation waste and binders as construction materials for liquidation of flooded mining workings.

    The use of waste from power generation in underground mining, moreover to positive effects for the environment, became necessary and common practice in such a technologies as grouting of gob, liquidation of workings or construction of backfill packs. However, the amounts of power generation waste being produced and the opportunities for much more large scale of application in mining induce searching of new composites that are made on their basis. This is related, between others, to use of them by the construction of isolation barriers. The paper presents an assessment of influence of selected natural additives on the general physical and especially filtration properties of fly ash-water mixtures made on the basis of waste from »X« power plant.
