  • Mining of Iron Ores – IspatGuru

    14/03/2014· Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines

  • Mining Underground mining | Britannica

    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 theОнлайн-запрос

  • Mining Technology in the Nineteenth Century | ONE

    Underground mining took place in both hardrock and placer deposits and used excavation, support, hoisting, ventilation, and drainage technologies. Early miners dug shallow shafts to reach the ore body, which they then followed to create "rathole" or unplanned underground workings. Engineer-designed or planned underground workings became more typical by the end of the nineteenth century.Онлайн-запрос
