Secondly, fly ash disposal sites must take necessary measures to restrain the re-entrainment of dust
during normal operation [10, 21, 22, 23]. For example, rational planning and partition running the disposal
sites to minimize the working face during storage process, setting up sprinkler system to keep ash surface
humid and increase cohesion between particles, layered paving and compacting fly ash during normal
operation timely, sprinkling water to the temporary rolling face timely, making sure the rolled hard shell
layer cannot be destroyed by disturbance, growing grass on the layered compaction permanent slope body,
reclaiming land when stockpiling height raises to the designed elevation, planting trees around the
disposal sites to restrain dust re-enterinment.
