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:
“Such as boxed
Their feelings properly, complete to tags
A box for dark men and a box for Other
Would often find the contents had been scrambled.”
—Gwendolyn Brooks (b. 1917)
“And if the stage-dark head rehearse
The fifth act of the closing night,
Why, cut it off, piece after piece,
And throw the tough cortex away....”
—Allen Tate (1899–1979)
