How Does The Process Of Deep Shaft Mining Work

  • How Underground Mining Works HowStuffWorks
    StoryExamplesComponentsCriticismsIn 2010, people everywhere were riveted to the story of the 33 miners in Chile trapped 2,300 feet (700 meters) underground in a copper and gold mine. The miners spent more than two months there, getting food, air and letters from loved ones through bore hills drilled to their location in a protected workroom. Meanwhile, the larger-scale drilling of an escape shaft made slow progress. Finally, on Day 69, rescuers lifted each of the minerMeer bekijken op science.howstuffworksAuteur: Julia Layton

    Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation is underground, it is called a winzeor a sub-shaft.
