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:
“All your lovely words are spoken.
Once the ivory box is broken,
Beats the golden bird no more.”
—Edna St. Vincent Millay (1892–1950)
“They give us a pair of cloth shorts twice a year for all our clothing. When we work in the sugar mills and catch our finger in the millstone, they cut off our hand; when we try to run away, they cut off our leg: both things have happened to me. It is at this price that you eat sugar in Europe.”
—Voltaire [François Marie Arouet] (1694–1778)
