coal mining is linked to coal preparation plant performance which is in turn linked to coal sales.The process of the CHP involves coal receipt from various systems and then unloads the coal at various unloading stations (See figure No 4). Then the coal is process as per requirement. After the processing it is to be transferred to bunker or stack yard. For controlling all these process the processes are equipped with control system. All theThe main goal of coal quality control in lignite mines is to supply coal to power plants within certain quality constraints. Coal properties can affect the efficiency,
2014· PCA recognized that coal mining and active mine fires (57.71% variance) are the main contributors of air pollutants in the study area. Vehicular emissions (17.85% variance) and windblown dust through unpaved roads and over burdens (7.54% variance) are the other causes of air quality deterioration around the coal mining areas.The coal quality is an important aspect of coal mine planning.
