[0027] The present disclosure generally relates to localized dust collection systems for use on off-road excavation equipment. figure 1 A first local dust collection system 20 on a piece of off-road excavation equipment in the form of a surface mining machine 22 is shown. During excavation operations using the surface mining machine 22, the local dust collection system 20 captures dust generated by the cutting drum 24 (i.e., the excavation drum) of the surface mining machine 22, thereby reducing the amount of dust that is released / exhausted into the atmosphere . Dust is extracted from a localized volume around the cutting drum 24 . The localized volume is bounded / defined by a shroud assembly 48 that surrounds / covers at least a portion of the cutting drum 24 .
[0028] It is understood that the enclosure may include various sealing structures for controlling or limiting the flow of outside air into the localized volume. Example sealing structures are disclosed in PCT / US2010 / ...
