The dangers of coal dust are inhaling the dust which goes into your lungs and skin irritation from dust. Coal dust is harmful for the most part and has no health benefits.
Particulate coal
any concentration of dust is potentially explosive
Coal dust is a physical toxicant. This is because it is a real thing with real effects.
Dangers can include fire/explosion, cave-ins of underground mines, flooding, inhaled rock and coal dust, noise from mining equipment, electric injuries (most underground equipment is electrically driven, and having a chunk of the rock ceiling fall on you. Being struck by equipment is a hazard, and when working narrow seam coal, developing "Miner's knee" for working on your knees- not enough room to stand up. I inspect coal mines, and these are some of the areas I look for.
Yes
Coal miners work in a freshly cut hole in the ground, right up close to heavy machinery, underneath a roof that can drop rocks on top of them. Coal dust can explode. Plenty of dangers right there.
Soot is another word for coal dust.
Particulate coal
Inhilation of coal dust, wet gas, explosion, roof falls, lost of eyes due to particals of dust hitting the eye without protection, being crushed by the horse drawn drams, loss of limbs due to cutting accidents, fires and flooding
Coal mines, coal bins, coal hods, and anywhere coal is or was.
Coal workers pneumoconiosis (CWP), is caused by inhaling coal dust.

There are several nasty things that inhaling coal dust can do but the commonest one was pneumoconiosis.Pneumoconiosis is caused by dust in the lungs usually after prolonged environmental or occupational contact.Anthracosis (an-thrah-KOH-sis),also known as coal miner's pneumoconiosis or black lung disease, iscaused by coal dust in the lungs(anthrac means coal dust, and -osis means abnormal condition or disease.

Coal has only one advantage relative to oil, which is that it is abundant and relatively inexpensive. Disadvantages include, it is more polluting (due to impurities in the coal) and it is harder to handle; oil can be pumped, whereas coal has to be shoveled. Coal mining is often more difficult and dangerous than pumping oil out of the ground. Coal dust creates the dangers of explosion, and black lung disease.
The answer is culm.
