Crushed stone is used for concrete aggregate, for road building, and, in the case of limestone, as flux in blast furnaces and for chemical applications. The quarrying technique consists ofdrillingand blasting to fragment the rock. A large number of charges are fired at one time, producing up to 20,000 tons of broken stone in one blast.
Extraction Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made.
Thismethodofquarryingis employed for the rocks which are in the form of layers along which it can be easily splitted (e.g. sedimentary and soft rocks likelimestone, marble, slate and laterite, etc.), and the stone is required in blocks for building purposes.
Blasting was used on the first layer of limestone. Dexpan was used on the second and third layers of limestone rock, as you can see, it produces much lesser damaged limestone. Stone Production and safety are both increased greatly.

About 10–15 cm deep holes, at around 10 cm spacing, are made vertically in the rock. Steel pins and wedges or plugs (conical wedges) and feathers are inserted in them. These plugs are then struck simultaneously with sledge hammer.
Quarryingis a type of mining and is also called as open pit mining or strip mining. When minerals are found profound beneath the surface, a deep mine has to be dug to dig out them.Quarriesare normally dug deeper and bigger; awaiting the mineral resource is worn out.

Themethodused to extractlimestonefrom the earth’s crust, which includes the topmost surface of the various layers of soil, is known asquarrying. Also known aslimestone quarrying, the practice has been debated hotly all around the world.
The ancient Egyptians used a wedge and feather method for their limestone blocks, and even then the practice was considered old. Nonetheless, it is still widely used today for its simplicity and cost effectiveness. Feathers (see picture) are first placed into holes drilled in a successive line.
Limestones have been worked for many thousands of years — initially for building stone and agricultural lime and more recently for a wide range of construction and industrial uses. In most industrialized countrieslimestone quarriesrepresent the most visually obvious and, in both process and landform terms, the most dramatic anthropogenic impact on karst terrain. However,quarryinghas, to ...
