As mining advances, a grid-like pattern of rooms and pillars is formed. When mining reaches the end of a panel or the property line, retreat mining begins. In retreat mining, the workers mine as much coal as possible from the remaining pillars until the roof begins to fall in (aka. third mining or 'robbing the pillars'). When retreat mining is completed, the mined area is abandoned.

Coal Exploration and Mining Geology

Sep 19, 2019· Definition and formation: Coal balls are calcareous masses of fossil peat found in coal beds. They are formed in the original peat before it undergoes coalification (DeMaris and others, 1983; Scott and others, 1996). Individual coal balls can be inches to many feet in diameter, and coal-ball clusters may occupy a small part (concentrated along the top or bottom) or the entire height of a seam.

Coal Exploration and Mining Geology

The debris must be buried, compressed and protected from erosion. Even though all the biological, geographic and climatic factors may be favourable, coal could not be formed unless the plant debris was submerged and buried by sediments. There are four stages in coal formation: peat, lignite, bituminous and anthracite.
