 abstract={The wastes created in the hard coal mines arc more and more significant because ofhigh request for aggregates and mineral mixtures to road and highway building. The paper presents that, despite the lowering of the factor of wastes created by coal production, the amounts of wastes created by current coal extraction arc still high and in the 2006 their amounts in Kompania Węglowa achieved 14,6 mil. tons (tab. I). In the further part of the paper, the possibilities of mineral aggregates production were discussed in the example of chosen mines KW S.A. and their application in building and road branch (tab. 6). In the example of KWK .. Bielszowice" the currently existing technological installation of mineral aggregates production was precisely characterized (fig. 2, 3) and the concept of its development was presented (fig. 4). Also, the modem solutions of similar installations were presented for ..Halemba" and .Marccl" mines (fig. 5). In the paper. also some physico-mechanical properties of the aggregates from coal wastes were characterized (tab. 2. 3. 4), as well the researches and law and technical procedures were discussed, which arc performed by mines in the purpose of achieving possibilities of introducing these aggregates to the market.},
