"EXPERIMENTAL STUDY OF THE QUARRY WASTEWATER FILTERING IN COARSE-GRAINED MASSIFS OF ROCK DEBRIS AT KAMYSHANSKY OPEN PIT MINE"

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.

Open pit mine wastewater filtration in the overburden rock debris: case study

“…It's distinguished the conventional plane of comparison 0-0. Without taking into account velocity pressures, which are extremely low in real conditions of filtering water motion in the body of the WWTF, and with the head in any flow section equal to the mark of free water surface in this section [26][27][28], it was expressed the head H in the section of point 2 above the comparison plane 0-0 through the height of water column h, measured vertically:…”

Features of Degassing from Overburden Rock Massifs: A Case Study Using Radon

“…Two patterns were considered in the present research: a large bulk massif and the distribution of overburden rocks in a shallow-gully network of valleys. The rocks display a wide range of fractional compositions from block to clayey debris [5,6]. Generally, the massif has a somewhat organized composition, characterized by a certain change in the size of the debris from the lower part of the massif to the upper part.…”
