  • Underground Mining Methods and Equipment

    Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are too great to commence a surface operation  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 collapseWhat is Underground Mining? (with pictures)When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be consideredMining Underground mining BritannicaUnderground mines have changed their operation systems in accordance with the evolution of equipment, the system and method of mining Transport is also of critical importance in underground mines as is the mining operation itself The underground transport system of ores, materials, equipment and persons has been developed fromUnderground Mining Transportation SystemsJul 12, 2016 Underground Miners Mining Australia See more ideas about Underground, Australia, Mining10+ Underground miners ideas underground, australia, mining
