THE LOW-COST TECHNOLOGY OF QUARRY WATER PURIFYING USING THE ARTIFICIAL FILTERS OF OVERBURDEN ROCKM. TYULENEV, S. ZHIRONKIN AND O. LITVINAbstract Influence of open-cast mining of mineral deposits on environment is substantial. It includes change of a landscape, violation of hydrological conditions and water and air pollution. But the greatest pollution of mining enterprises is being caused to surface water sources. It is caused by high maintenance of a suspension and other contaminants in the disposal water, its considerable volume and rather low efficiency of purifying facilities that doesnt allow proper waste water purifying to the norm of disposal. The article contains a description of the filtering rate characterizing the intensity of suspended material grains settling in the pores of the filter array. The change of the filtering rate on the height of the filter array is described. The technology that allows improving the quality of open pit waste water purification is presented. The schemes and location of artificial rock arrays currently exist on several open pit coal enterprises are given.
