  • Coal mining and coal combustion in power plants produce several types of wastes The mining process itself produces waste coal or solid mining refuse which is a mixture of coal and rock The mining process also produces liquid coal waste which is then stored in impoundments Pollution control equipment used for coal combustion produces coal ash or fly ash as well as flue gas The minerals and associated non mineral inorganic elements may give rise to deleterious effects during coal preparation and utilization such as stickiness and abrasion during preparation and ash deposition issues corrosion erosion and release of volatile pollutants such
