They are used in the form of aqueous suspensions in various mining technologies on the basis of environmental and technical requirements defined in adequate regulations and standard PN/G-1 I O 11. The standard sets requirements for material samples after 28 days of seasoning. There is a lack of studies which evaluate properties of samples seasoned for a longer period of time, especially in natural conditions. The author received samples from 7 mines. The samples were excavated after a few years of staying underground. They were tested in the laboratory after adequate preparation. The test results are presented in the paper.}, title={Properties ofwet fly ash suspensions seasoned in hard coal mine underground}, type={Article}, URL={http://czasopisma.pan.pl/Content/133614/PDF/10_GSM_24_4_1_2008_Piotrowski_Properties.pdf}, keywords={Fine grained waste, underground mining, mining technology, fly ash-water suspensions}, }
