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?
    Drill pipe turns the drill bit to cut into rock until it reaches deposits, while casing pipe is tubing set inside the drilled well to protect and support the well stream.
  • Where does overburden go during a mining operation?
    Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete.
