How Does Marble Get Mined From a Quarry? | Sciencing
Apr 24, 2017· The bench wall is a large section of marble along a vertical wall that is cut with diamond cables, drills, and torches. Dynamite loosens the bench wall from the side of the quarry, and the separated wall can then be processed and cut into individual, uniform blocks. A marble block usually weighs between 15,000 and 25,000 pounds.
