Summary: A hand-held coal and rock dust sampling devise suited to collect consistent mine
dust samples
Description: Mine dust in underground coal mines is potentially explosive and must be sampled
regularly. Samples are then analyzed in the laboratory to confirm that there are at least 80%
inert components in the sample to prevent devastating coal dust explosions. A hand-held coal
and rock dust sampling devise suited to collect consistent dust samples off of the mine floor,
ribs, and roof as well as other surfaces where mine dust settles has been designed and tested.
The advantage of this sampling method, over current pan and brush methods, is that the devise
mimics the dust entrainment process that happens in an explosion. Thus, the samples that are
collected are more representative of the portion of mine dust that would be scoured up during
an explosion.
Main Advantages of this Invention
 Provides more representative mine dust samples
 Samples can be collected from elevated, inclined, vertical, and inverted surfaces
Potential Areas of Application
 Coal mining
Stage of Development: laboratory tested prototype
