The ETS requires mine operators to increase the incombustible content of combined coal dust, rock dust, and other dust to at least 80 percent in underground areas of bituminous coal mines. The ETS further requires that the incombustible content of such combined dust be raised 0.4 percent for each 0.1 percent of methane present.

Comets are made of frozen gasses and bits of rock and dust. The solid part of most comets can be up to 10 miles across. As a comet gets close to the sun, the heat causes the comet’s frozen gasses to turn into a cloud of vapor and dust. The cloud can be thousands of miles across. Solar winds cause this vapor cloud to trail out behind the comet

Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.
