    W.H. Langer, in Encyclopedia of Materials: Science and Technology, 2001. 4.1 Quarrying. The quarrying operation cuts a block of stone free from the bedrock mass by first separating the block on all four vertical sides, and then undercutting or breaking the block away from the bedrock. If the block is large, it is called a “quarry block” and will be cut into smaller blocks at the quarry.
