Abstract
Surface run-off is water from rain and snowmelt flowing from the territory of industrial enterprises. The part of surface run-off in the total volume of discharged wastewater from the coal industry is 2%. Their volume depends on the amount of rain and melt water, as well as the size of the sites of industrial enterprises. The objects of surface run-off contaminants in the Novovolynsk mining area are: outdoor coal and concentrate storages, colliery spoil heaps, sludge and tailings, crushing compartments, storages fuels and lubricants, points of railway cars loading and unloading, cable cars, boiler installations, etc. On the territory of the Novovolynsk mining area besides the wastewater a huge amount of mining waste is formed. It is stored on flat heaps, adjacent to the area. Coal also accumulates on flat dumps. The surface run-off from the area of the flat heaps may contain chemical compounds. Surface water from the mine area is not purified, although in terms of quality, it is highly polluted. During investigation period the Novovolynsk mining area the storm run-off from their territory contained more than 15,000 mg / ml of suspended substances and up to 500 mg / ml of petroleum products [4]. Spoil heaps are the main sources of surface run-off contamination by suspended solids, mineral salts and heavy metal ions. Thus, the amount of suspended solids in rainwater reaches 12000 mg / l and in meltwater - up to 50,000 mg / l, the total salt content reaches 8000 mg / l. The maximum amount of iron is more than 7550 mg / l. It is found in the meltwater from the spoil heaps of almost all mines in the Novovolynsk mining area. The composition and concentration of pollutants in coal storage water runoff doesn't differ too much from the spoil heaps water run-off. An extremely important factor of man-made impact on the sanitary status of natural water bodies is the pollution of the water-intake areas around coal and mining enterprises by chemical elements, especially during polymetallic ores development [2].
