Victorians used to use coal as make up like lipstick and eyeshadow and you can eat it if you sterilise it and mix it with something :D
No, coal is not a carbon sink. In fact, burning coal releases carbon dioxide into the atmosphere, contributing to climate change.
Not sure if this will answer your question, but I'll give it a shot. It's less about the fact that is is coal and more about the fact that coal gives off heat. When coal was first being used as a heat source, it was cheaper than wood and there was a lot of it. So really the origin of the energy is in the heat that the coal generates when on fire and less about the coal itself.
Coal is not from any "big gap" . It is a solid part of the subterranean strata. In fact a big gap is left when coal is removed.
Coal is not considered pure because it is typically composed of a mixture of different organic and inorganic materials. The composition of coal can vary depending on the type and age of the coal deposit.
No, coal is not the hottest burning substance. In fact, coal burns at a lower temperature compared to other substances like natural gas or hydrogen.
Yes, burning coal is exothermic, in fact, that is why people burn coal. It produces heat.
coal is used to make a fire and is also a mineral
Carbonite was used as an explosive in coal mines because it was the safest material to use. This is due to the fact that most of the carbon is bound into carbon monoxide.

A fact about the Canadian wildness is the Moose and the interesting trees. And the big lakes the mine for coal too.
Waste coal is one of many names (overburden, gob, culm, bony, coal refuse etc) for an organic rock material that is generally found at or near a coal mine site/mine. It is a rock generally consisting of a combination of some carbon (coal) and indigenous rock material commonly found at or near the mine site. Since it has some but low BTU value compared to commercial grade marketplace coal it is referred to as waste coal or coal refuse today. In the past millions of tons of (prior to 1980's) the material was commonly discarded due to the fact that there wasn't a commercial use for the material. Since then a new technology was developed called CFB (Circulating Fluidized Bed) that can cleanly convert low value BTU material (such as coal refuse) into clean coal alternative energy. Today there are approximately 20 power plants in the USA removing coal refuse from our landscape and converting it into clean alternative energy...in an environmentally beneficial manner...in fact 10% of the energy generated in PA is made from coal refuse. Yesterdays waste has become today's alternative energy
