The research of environmental-and-economic risks of the coal mining enterprise impact on water resources

Abstract

Coal mining enterprise is a high-tech complex with a significant negative impact on water resources in the form of wastewater discharge. To improving the environmental safety of enterprises having a negative impact on the aquatic ecosystem, it is necessary to detail its features in order to increase the efficiency of environmental management. The article analyzes known approaches to the definition and features of formation of systems of assessing the negative impact on water resources. On the basis of synthesis of theoretical developments of domestic and foreign researchers` study and analysis the actual data of an industrial enterprise authors researched its negative impact on water resources to form a program of effective water protection measures. This researching has practical importance for large industrial enterprises that have a negative impact on water resources for effective environmental management decision-making.

Exploration of Environmental Protection-Oriented Ecoenvironmental Performance Audit System

“…( 1) With the construction of dams, hydropower stations, and other water conservancy facilities, the main Yangtze River and many tributaries are no longer directly connected with the upstream, midstream, or downstream, and many rivers are blocked. (2) Due to the demand for water storage and flood control, the natural fluctuation law in the Yangtze River Basin has been affected, and because of the changes in water temperature, water quantity, and hydrological law in the Yangtze River Basin, the dry season of the Dongting Lake and Poyang Lake in the Yangtze River Economic Belt has advanced, which brings great challenges to the protection of the lake ecology [11]. (3) With the acceleration of urbanization, there are many sand mining sites in the Yangtze River Economic Belt and the speed of sediment exploitation has exceeded the limit of natural recovery in the Yangtze River Basin, which has made the water quality safety and the living space of aquatic animals seriously threatened.…”
