transportation and preparation of minerals to minimise
emission of flammable dust.

Where such dust is emitted into the mine
atmosphere either below ground or on the surface, measures
should be taken to ensure that the dust is trapped as near as
possible to the point of origin.

Accumulations of flammable dust should be
cleaned up and transported out of the mine or rendered
harmless without delay.

(1) No plant for screening or sorting coal should be
placed within 80 m of a downcast shaft, drift or adit unless

minimise the possibility of dust entering the downcast air
stream.

be maintained in good condition so as to minimise spillage.
