The quarrying process consists of separating large blocks, sometimes called loafs, from the surrounding rock. These blocks may be 6 metres high by 6 metres deep and 12 to 18 metres (about 40 to 60 feet) long, and they may weigh in the range of 1,200 to 2,000 tons. (Such large blocks are subsequently divided into mill blocks weighing 15 to 70 tons.)Underground Quarrying for Marble: Stability Assessment ,indirect methods allows one to define the fracturing state of the rock or the related physical properties (mechanical wave velocity and other geophysical parameters).The convergence measurementsImpact of Stone Quarrying on the Environment and the ,Stone quarrying is a form of land use method concerned with the extraction of nonfuel and nonmetal minerals from rocks [1]. It is usually done by opencast method using rock drills, explosion of dynamite and use of other methods [2]. Quarrying has environmental and health effects.
