The Unpredictable Life Cycle of a Coal Pillar

2012-8-30 · throughout the mining cycle without reaching peak strength, this pillar is termed a "stiff" or "large" pillar. For the region up to the peak strength (B), the coal behaves elastically and elastic-plastic after yield begins. After the pillar peak strength has been exceeded, the pillar will still have some load-bearing capacity or residual

12 Environmental Effects of Coal Mining

Possibly one of the scariest environmental effects of coal mining is the threat of acid rain. The high acidity of AMD remains in the water supply even through evaporation and condensation, which enables it to stay in the atmosphere and eventually return in the form of "acid rain," thus perpetuating the cycle of pollution.
