    Mining Underground 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,...

    Techniques in Underground Mining

    Ore handling. On its route from the stopes to the hoisting shaft, the ore passes several stations with a variety of materials-handling techniques. The slusher uses a scraper bucket to draw ore from the stope to the ore pass. It is equipped with rotating drums, wires and pulleys, arranged to produce a back and forth scraper route.

    Processing or Dressing the Ore Mining Equipment

    Processing or Dressing the Ore. Additional crushing of the rock was needed before grinding, also metals like copper, iron, lead, zinc, tungsten and arsenic were mixed with the tin. These metals concentrated with the tin and were removed by additional “cleaning” processes, thus the “dressing” or milling of underground ores became a more costly and difficult operation.
