Bench blasting is the most widely used method of production blasting in quarrying strip mining and construction excavation This involves drilling inclined vertical or horizontal blastholes in single or multiple row patterns to depths ranging from a few meters to 30 m or more depending on the desired bench height
Dimension stone is quarried by cutting or separating by some other means large blocks of stone from the natural rock mass The size of individual block produced depends on a number of factors including the homogeneity of the rock itself the ability of the quarry operator to handle the rough stone and the required end use for the stone once it has been shaped
Mining Quarrying Extraction Processing Although seldom used to form entire structures stone is greatly valued for its aesthetic appeal durability and ease of maintenance The most popular types include granite limestone sandstone marble slate gneiss and serpentine All natural stone used for structural support curtain walls veneer floor
