The document discusses the design and operation of a coal handling plant (CHP) system with two stages. The CHP transports coal from mines to bunkers and maintains the correct size, quality, and quantity of coal. Stage I has a capacity of 1250 MT/hr while Stage II has a higher capacity of 1500 MT/hr. The CHP includes conveyor belts, coal crushers, bunkers, stockpiles, and transport hoppers. The document provides details on the layout, equipment specifications, coal quality parameters, and operating procedures of the multi-stage CHP system.
