Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground. ...

Research and practice in mining engineering have summarized five major hazards common in the coal production process: water, fire, gas, coal dust, and roof. These disasters are sources of hazards formed by substances or energy that coexist with coal in the natural environment and evolve into accidents when they get out of control during coal ...

Mining. In Australia, nearly 80% of coal is produced from opencut mines, in contrast to the rest of the world where opencut mining only accounts for 40% of coal production. Opencut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the resource.
