  • Underground Mining, Underground Mining Equipment

    Underground mining is carried out when the rocks, minerals, or precious stones are loed at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.
