Assessing the Design, Size, and Operation of Sediment Ponds .

include works such as mine pits, benefaction plants and related facilities, mine waste rock dumps, tailings ponds , roads, and ditches. Mining companies are responsible for minimizing erosion from disturbed areas and for collection and treatment of runoff from these areas before it is discharged into the receiving environment.

Coal waste - Global Energy Monitor

Before burning, coal is crushed and washed, creating waste water filled with toxins. Another form of liquid coal waste is acidic mine runoff. Both forms of liquid coal waste are disposed of in a landfill at the mine site.

Study on Heavy Metal Contamination in High Water Table Coal .

Since the groundwater level in regions with a high water table is high, a large subsidence pond will form after a coal mine has collapsed 1 . This not only drastically decreases the land area but also affects the ecological structure to some extent and disrupts the ecological equilibrium.

Best Practices For Dust Control In Coal Mining

many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers’ pneumoconiosis CWP . CWP is a lung disease that can be disabling and fatal in its most severe form. In addition, miners can be exposed to high levels of respirable silica dust, which can cause silicosis, another disabling and/or fatal lung .

MIW is defined as any water whose chemical composition has been affected by mining or mineral processing and includes acid rock drainage ARD , neutral and alkaline waters, mineral processing waters and residual waters.

Use of Air-and-Water Spraying Systems for Improving Dust .

Protecting mining personnel against air dustiness is usually limited to the use of personal protective equipment and water spraying systems in longwall shearers, roadheaders and at transfer points of conveyors. Water spraying used so far is found to be not efficient enough in dust control and it consumes a lot of water.

Study on Heavy Metal Contamination in High Water Table Coal .

Heavy metals accumulate in high water table coal mining subsidence ponds, resulting in heavy metal enrichment and destruction of the ecological environment. In this study, subsidence ponds with different resource reutilization methods were used as study subjects, and non-remediated subsidence ponds were collectively used as the control region to analyze the heavy metal distributions in water .

The most studied case of coal ash damage occurred at Belews Lake in North Carolina in the 1970s, when coal ash-contaminated water from an ash pond at Duke Energy’s Belews Creek Steam Station caused a long-term astrophic toxic event. Selenium poisoning killed 19 of the 20 fish species in 3800-acre Belews Lake.
