Abstract
The development of open pit mining in the large coal basins of Russia and other countries increases their negative impact on the environment. Along with the damage of land and air pollution by dust and combustion gases of blasting, coal pits have a significant negative impact on water resources. Polluted quarry water worsens the ecological situation on a much larger area than covered by air pollution and land damage. This significantly worsens the conditions of people living in cities and towns located near the coal pits, and complicates the subsequent restoration of the environment, irreversibly destroying the nature. Therefore, the research of quarry wastewater purifying is becoming an important mater for scholars of technical colleges and universities in the regions with developing open-pit mining. This paper describes the method of determining the basic parameters of the artificial filtering arrays formed on coal pits of Kuzbass (Western Siberia, Russia), and gives recommendations on its application.
Highlights
Industrial complexes concentrated in the most developed part of the biggest Russian coal basin – Kuzbass (Kemerovo Region, Western Siberia) – have the decisive influence on the ecological condition of environmental objects [1]
For using waste dumps or any other similar arrays of rock in water purification schemes it is strictly necessary: - to choose one or another particular dump and identify the ways of supplying and discharging water; - to test the ability of the dump to pass all the clarified water at the given water disposal in the period of maximum flow; - to test the ability of the selected dump to clarify water to the maximum permissible concentration rates
Development of effective quarry water purifying technology requires cooperation of technical universities, research organizations and mining enterprises for saving the environment in coal basins. Geoecological effect of this technological platform is connected with the growth of wellbeing of communities located near open pits
Summary
Industrial complexes concentrated in the most developed part of the biggest Russian coal basin – Kuzbass (Kemerovo Region, Western Siberia) – have the decisive influence on the ecological condition of environmental objects [1]. The decrease of production from the mid-1990s in the coal-mining areas of Kemerovo region has not led to the improvement of its environment [2,3]. The negative effect made by coal-mining enterprises on the natural environment has complex origination. We observe an intensive pollution as a result of the influence of coal deposits open-pit mining on the atmosphere, water resources and landscape complexes. The volume of coal production in Kemerovo region amount to more than 210 million tons per year [6,7]. According to the report of supervisory environmental authorities in 2015, coal-mining enterprises of Kemerovo region disposed 1.239 billion m3 of wastewater, including inadequately treated – 228.8 million m3 [8,9]
