Both river rock and limestone quarries will also produce select fill, common fill, washed sand, and various construction rocks ranging from crusher fines, 3/8"-1" rock, 2"-6" bull rock, and 6"-36" rip rap. Some materials are much more common ...
At the quarry, it can take months before any marble is able to be extracted from the earth. 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.
