Coal is mined from underground. Workers and machines take out coal from underground.
they mined rocks for coal.
Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining.The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.
If shallow then it is mined using a "strip" mining technique. If it is deep then it is mined in deep mine collieries.
After the coal is mined, the workers ship it off somewhere where they start to sell it to some stores so people could buy it

Coal is mined from underground.
The answer is Brown Coal
Coal may be mined in underground mines, typically by machinery that pulls the coal from the seams, and transports it to the surface. Coal is also mined in surface mines by removing the soil and rock on top of the coal, and then using machinery to break the coal from the seams, and move it to storage.
Geological conditions of the earth surface or UG surface decide where we mined coal. And also depth or thickness of coal seam.
Brown coal is mined at La Trobe Valley, Victoria, Australia.
Just about any mineral or metal can be mined underground or at the surface. Some typical underground mines may include gold, silver, coal, uranium, limestone, and salt. Many gemstones such as opal, diamond, emerald, ruby and sapphire are found in underground mines.
Coal is also mined by underground mining, but only a portion of the coal present can be removed (holds up the roof). Coal is also mined by high wall or long wall mining, and by using large diameter augers to dig laterally into exposed seams.
it is mined by using a giant bucket wheel excavates or dredgers. they are loaded onto a conveyor belts for delivery to power stations.
Coal is deposited usually in layers, underground, sometimes fairly close to the surface.
