Coal stockpile systems are designed for a particular capacity and have equipment designed to achieve those rates. Where there is a change in the design parameters of the coal stockpile such as stockpile or reclaim capacity, or a change in the way the system is operated, there is a possibility that the change could result in a risk to people, equipment or the environment. A review of the hazards and risk control methods shall be conducted whenever coal stockpiles are significantly changed. Bulk material placed by tipping, discharge from overhead conveyors and trippers and dozing will contain areas of instability. Placement areas are not designed as engineered compacted fill and the degree of compaction, size and shape is constantly changing. In this paper are described methods that can be applied for reduction surface land affected of stockpile.
