Mining marble blocks from the wall of the quarry starts with a "bench wall." 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.
Dec 13, 2018· Coring drills are equipped with a water pump to flush cuttings to the surface between the hole wall and drill pipe. For mineral exploration, drilling techniques can be used to determine information about rock types, mineral content and more. There are a number of considerations that should be weighed when deciding which method to use.
