Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite and Sub-bituminous coal, but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.

Working in coal mines is dangerous — miners have to deal with toxic gases, plus the threat of being crushed, drowned, or injured from fires and explosions.
What does coal miner mean?
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
Is Coal still being formed?
The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.

Why is mining dangerous?
Mines are often home to many dangerous gases including carbon monoxide, hydrogen sulfide, methane, and carbon dioxide. Due to the confined spaces, these gases are not always able to escape, building up within the mine. … Following a methane explosion, consecutive coal dust explosions can also occur.
