Mine Supervisor Disposal of Coal Mine Slurry Waste

plant, the fine rock particles are suspended in water forming a slurry. This slurry is normally disposed of via surface impoundments or injected into abandoned underground mine workings. The volume of this waste stream is very significant and expensive to dispose of. At the North River Mine approximately 1,000 gallons per minute is created on a 24-hour basis. In 2007, a possible interruption ...

Coal slurry - Wikipedia

Ideally, coal slurry consists only of crushed coal and water, which can be efficiently separated. In practice, the separation is significantly costly due to the large amounts of water needed and wastewater generated by the process. Furthermore, the slurry consists also of very fine coal dust that results in a waste called blackwater. As blackwater cannot be purified by a water treatment plant, it is stored in large impoundment ponds. Such ponds are susceptible to disastrous releases, such as the Buffalo Creek flood of 1972 or the
