Faqs:
  • What is drill casing in mining?
    In underground mining, steel casing or steel pipe is used to line holes that have been bored or drilled for rising mains water, utility lines, and paste fill, protecting the contents from damage and loss into open voids or broken ground.
  • What is the difference between drill pipe and casing?
    The drill bit is rotated by the drill pipe, cutting through the rock until it reaches the deposits. Casing describes the tubing installed within the drilled well to support and shield the well stream.
  • Where does overburden go during a mining operation?
    Overburden is used as a building and road construction material, for reprocessing, and for contouring land. Reclaimed mine tailings are used to make concrete, glass, tiles, and clay. Mine water is cleaned and used as a coolant, in industry and agriculture, and to control dust and particulates.
