    Mining Mining Underground mining: 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 considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on RADIO FREQUENCY COMMUNICATION SYSTEMS IN ,Leaky feeder based RF communication system[1-3] would be established for communication in mine labyrinth gallery in recent future. The carrier current system working on induction theory was used for shaft communication and also experimented in galleries for line-of-sight communication working on the same principle.

  • What is Underground Mining? (with pictures)

    Nov 02, 2019· 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,
