Abstract
Improvement of the Mine Water Purification Efficiency via Modified Settling Tank
Highlights
The coal mining industry is a powerful manmade factor influencing the environment, causing negative transformations and pollution on adjacent territories, surface reservoirs and groundwater
It was established that the implementation of the proposed technological scheme of mine water purification will reduce the concentration of suspended solids to the normative concentrations allowed for discharge into surface water bodies
The calculated values of the hydraulic size (Ui, mm/s), which characterize the mode of sedimentation of the suspended particles in the proposed settling tank at a given percentage of purification efficiency of mine water (P, %) are presented in the Table 5
Summary
The coal mining industry is a powerful manmade factor influencing the environment, causing negative transformations and pollution on adjacent territories, surface reservoirs and groundwater. The mine water discharges pose a threat to the environment and the population of coal-mining regions due to huge influx values and specific physicochemical properties (Rules for protection of surface waters from return water pollution, 1999). The discharge of contaminated mine water into adjacent surface water bodies is an environmental hazard. Almost all mine water is more or less contaminated with suspended solids (in the form of small particles of coal and rock). The mines of the Western Donbass (Ukaraine) annually discharge up to 0.1 thousand tons of the suspended substances into water bodies The mines of the Western Donbass (Ukaraine) annually discharge up to 0.1 thousand tons of the suspended substances into water bodies (Kharitonov M.M. & Anisimova L.B. 2013)
