Landscaping of the quarry site after exhausting the quarry product may improve the areas natural beauty. Despite the benefits, quarrying also has negative impacts. The blasting needed in extracting the rock contributes
Quarrying is the process of removing rock, sand, gravel or other minerals from the ground in order to use them to produce materials for construction or other uses. So, a quarry is any such working on the surface of the earth where minerals are extracted. Quarries are also known by other names around the world: ''surface mine'', pit, ''open pit'' or ''opencast mine''.
Sand, gravel, and crushed rock quarries employ standard surfacemining techniques. 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 of drilling and 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.

Blasts in coal mines are typically the largest in the mining industry. Poorly designed or executed cast blasts and presplits have a high potential to generate vibration, overpressure and flyrock. Careful blast design and planning, combined with prediction, measurement and reconciliation of results is the key to controlling and managing these outcomes and maintaining a good relationship with
Quarrying is the process of obtaining quarry resources, usually rocks, found on or below the land surface [1]. The difference between mining and quarrying is that quarrying extracts nonmetallic rocks and aggregates while mining excavates the site for metallic mineral deposits. Some of the stones extracted are sandstone, lime

Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or openpit mines) and closed types (mines and caves). For thousands of years, only hand tools have been used in quarries.

Mining and Quarrying ImpactsIntroductionMining and quarrying extract a wide range of useful materials from the ground such as coal, metals, and stone. These substances are used widely in building and manufacturing industry, while precious stones have long been used for adornment and decoration. Mining and quarrying involve investigating potential sites of extraction, then getting the required
