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 drill holes, 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.Mining marble from a quarry involves creating a bench wall, which requires synthetic diamond wire and diamond-tipped drills to separate the rock to form a vertical plane. This involves drilling holes in the marble from the top of the quarry and lining up another drill hole from the side.From Quarry to Countertop: How Marble and Granite Are MinedIn ancient times, during the Roman age, when the exploitation of Carrara quarries began, the cutting was done with manual methods which implied the separation of the marble bench wall from the mountain through fracture. The oldest technique was the “tagliata”: the quarrymen, through the use of chisels, created cracks in the rock, especially ...Marble: the quarrying techniques – Carrara Marble Tourاحصل على السعر

But once it is, the process can finally begin. Dynamite is used to loosen the marble from the walls of the quarry, and then the stone is cut into blocks. Each block weighs roughly 15,000 to 25,000 pounds.Marble Quarries: What Are They? | Marble.comIn ancient times, during the Roman age, when the exploitation of Carrara quarries began, the cutting was done with manual methods which implied the separation of the marble bench wall from the mountain through fracture.
