  • Effect of aggregate stockpile configuration and layout

    In practice, many stockpiles are stored and loaded by forcing machine with special arrangement space in a real storage yard. In a general manner, coal is stocked via a combined stacker reclaimer which runs parallel to the piles along the centre rail track. Wheel loaders and mobile hoppers are used to load coal into trucks or trains.

  • Prevention and Control Module for Spontaneous

    Proper dimensioning of stockpiles helps negate weathering of coal. Just dumping the coal in a big pile might lead to problems. Rather coal should be packed in horizontal layers of about 1.3 to 3 feet high followed by leveling and compaction by dozers. It helps in evenly distribution of coal thus avoiding segregation of fine coal.

    Spontaneous combustion of coal is one of the major problems in the coal mine. The fire may occur due to exogenous and endogenous causes, by which coal liberated heat to the air or heat absorbed into it. It causes loss of production, as well as economical or financial losses and polluted the environment. If, the heat liberated during this process is allowed to accumulate, the rate of reaction ...
