Abstract: Both open-pit and underground coal mining produces a significant amount of wastewater. These waters are contaminated with suspended particles and dissolved substances. Industrial filters are used for the treatment of such wastewater, consisting of settling ponds, filter dams, purified water collection ponds and bacterial UV treatment stations. Filter dams, along with their relatively small size, have one big disadvantage: their construction requires a special filter load. Ceramzite, zeolites and specially produced sorbents are used as fillers for such loading. As an alternative to using expensive materials for mine’s wastewater filtration, it is proposed to use overburden rocks.
In order to assess the suitability of overburden for use as a filter material, it is necessary to carry out a corresponding study, which will consist in the construction of an experimental filter massif, the filtering of cjntaminated quarry water through it, the sampling of water and rocks, analysis of data.
This paper describes the experiment on quarry wastewater treatment: the problem statement is considered, the assumed factors influencing the treatment process and their corresponding responses are established; some results are given. The order of realization of experiment, ways of measurement and calculation of observed responses is described. The received data will be used as initial at calculation of optimum designs and lithological compositions of filtering dams in water treatment systems at the enterprises of «SUEK-Kuzbass» JSC.
