Dec 22, 2012 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.

CN102383857A Gob side entry retaining process for solid

The invention relates to a gob-side entry retaining process for solid-filling, coal-mining and laying a gangue wall. The gangue wall is laid at one side of a filling body in a gob on a filling and coal-mining surface and is laid into a wall body by filling gangues in a coal mine into a woven bag or a plastic woven bag to form a mining roadway on a next working surface.
