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:
“A box of teak, a box of sandalwood,
A brass-ringed spyglass in a case,
A coin, leaf-thin with many polishings,
Last kingdom of a gold forgotten face,
These lie about the room....”
—Philip Larkin (1922–1986)
“The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labor and sorrow; for it is soon cut off, and we fly away.”
—Bible: Hebrew Psalms, 90:10.
