Q

What are the steps to quarrying?

A
  • Long-bladed saw makes deep, long cuts into rock
  • Holes are drilled into the horizontal face of rock (to create a plane of weakness)
  • Rubber bladders are inserted and inflated into those cuts, causing slabs to fall away from solid rock
  • Steel wedges are driven into slabs, making smaller blocks
  • Blocks are shipped to mills
