COAL
TESTS

Before underground coal mines were ventilated, the miners took
canaries into the mine. If the bird died, the air was toxic and the miners
retreated. Methane gas (explosive in certain
concentrations) seeping from the coal seam is still a danger in modern coal mines. From

"Washed" means coal has gone
through a preparation plant to separate coal from binder slate
and other impurities.
"Free Swelling Index" and
"Coke Button" are measures of structural strength of coal when
it cokes.
