Equipment, such as wire saws and high-pressure water jets, are typically used for successful dimension stone quarrying. Wire saws can reduce wastage to about seven percent while producing blocks as large as 250 metric tons to customer specifications. Large multiblade block cutters can cut an entire block into 50 or more slabs at once.

12/02/2015· Today, the most common method to quarry the dimension stone is by cutting out the primary blocks with a wire gang saw. Diamond wire cables are threaded through the drillholes, and tightening the wire during the sawing results soon in large cuts. Sawing in this way is often the only means of extracting blocks of marble and limestone.
