Quarrying of Stones: Its Methods, Selection of

This method consists of using explosives for breaking stones from very hard rocks. It has been observed that quarrying of granites, basalts, traps, quartzites, and sandstones by wedging and other methods is very laborious and costly. These hard rocks, however, can be loosened economically and easily by using explosives. The basic principle of this method is to explode a small quantity of an explosive material at

Quarrying of stones - CivilEngineeringBible

The process of raking out stones from natural rock beds is known as the quarrying. The term quarry is used to indicate the exposed surface of natural rocks. The difference between a mine and a quarry should be noted. In case of a mine, the operations are carried out under the ground at great depth. In case of quarry, the operations are carried out at ground level in an exposed condition.

Mining and Quarrying Impacts

Quarrying is the cutting or digging of stone, and related materials, from an excavation site or pit and it usually leaves behind a large hole in the ground. An ore is a deposit containing an economically viable amount of a mineral, which itself is a crystalline inorganic compound, usually containing a metal. It is the metal that is of value. The main groups of minerals that are mined are oxides, sulfides, and silicates.

Quarrying is the breaking free and removal of rock fragments by shock pressures from breaking waves, water hammer, and the compression of air in rock joints. Although shock pressures and water hammer are generated by breaking waves, both breaking and broken waves can cause compression of air in joints. Air is compressed in joints and bedding planes as water rushes in, followed by a sudden

Blasting Quarrying and the environment

Blasting is necessary to break rock from the ground, prior to it being taken for processing. In the early days of aggregate quarrying, explosives were not used particularly scientifically although some attempts were made to optimise use to minimise cost and maximise output. In most cases, high explosives would be detonated instantaneously — either packed into near vertical drill holes or occasionally into
