What is Underground Mining? (with pictures)

2020-7-7  The first step in underground mining is development mining, in which shafts are dug into the site to make the ore accessible. During this phase, along with shafts, things like electricity are installed, along with lifts and shoring to support the walls of the mine so that it will not collapse. Once the mine is developed, active production mining can begin, with the ore being extracted by hand .
