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)
“Sickness disgusts us with death, and we wish to get well, which is a way of wishing to live. But weakness and suffering, with manifold bodily woes, soon discourage the invalid from trying to regain ground: he tires of those respites which are but snares, of that faltering strength, those ardors cut short, and that perpetual lying in wait for the next attack.”
—Marguerite Yourcenar (1903–1987)
