A box cut is a small open cut created to provide a secure and safe portal as access to a decline to an underground mine. Generally the box cut is sunk until sufficiently unweathered rock is found to permit the development of the decline. The portal is generally made safe with rock bolts, wire mesh, and shotcrete, which prevents accidental rock falls from closing access to the decline.
Famous quotes containing the words box and/or cut:
“If you like to make things out of wood, or sew, or dance, or style people’s hair, or dream up stories and act them out, or play the trumpet, or jump rope, or whatever you really love to do, and you love that in front of your children, that’s going to be a far more important gift than anything you could ever give them wrapped up in a box with ribbons.”
—Fred M. Rogers (20th century)
““Don’t let him cut my hand off—
The doctor, when he comes. Don’t let him, sister!”
So. But the hand was gone already.”
—Robert Frost (1874–1963)
