Coal mining Extraction, Processing, Pollution | Britannica
Coal mining Extraction, Processing, Pollution: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases.
Coal Mining in the UK During the Industrial Revolution ThoughtCo
Coal miners were paid by the amount and quality of the coal they produced, and they could be fined if there was too much "slack" (the smaller pieces). Quality coal was what owners required, but managers determined the standards for quality coal. Owners could keep costs low by claiming the coal was of a poor quality or rigging their scales.
