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:
“He holds the wire from this box of nerves
Praising the moral error
Of birth and death, the two sad knaves of thieves,
And the hunger’s emperor;
He pulls the chain, the cistern moves.”
—Dylan Thomas (1914–1953)
“My angel,—his name is Freedom,—
Choose him to be your king;
He shall cut pathways east and west,
And fend you with his wing.”
—Ralph Waldo Emerson (1803–1882)
