Quarrying is 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. Quarries are normally dug deeper and bigger; awaiting the mineral resource is worn out.

In other words a quarry is a big man-made hole in the ground from where minerals or rock are taken out. Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth's surface. Quarrying is a type of mining and is also called as open pit mining or strip mining.
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Open Pit Mine Planning and Design is an excellent textbook for courses in surface mine design, open pit design, geological and excavation engineering, and in advanced open pit mine planning and design. The principles described apply worldwide. In addition, the work can be
Geotechnical Considerations in Open Pit Mines Version 1.0 Department of Minerals and Energy Page 3 of 49 1.0 INTRODUCTION The potentially hazardous nature of open pit mining requires the application of sound geotechnical engineering practice to mine design and general operating procedures, to allow
Key words: Open pit mining, bench height, multi-criteria decision making. INTRODUCTION As a definition in open pit mining, bench height is the vertical distance between crest and toe of the bench (Fourie and Dohm, 1992). Determination of optimum bench height is a major concern in most open pit mines.
The mining laws, both Federal and state, guide the design of surface mines; significant regulations are summarized in Appendix A. The data obtained from the mine visits was utilized to prepare five case studies to show the area’s different Planning of open-pit mines on a business-risk basis (2)
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries are regulated in some jurisdictions to reduce their environmental impacts. The word quarry can also include the underground quarrying for stone, such as Bath stone

Data. The open pit operator RWE, then known as Rheinbraun, initiated the permitting process for open pit mining in 1974 and was able to commence operations in 1978.The first excavator began its work on 15 October 1978. This was accompanied by the resettlement of local villages and towns and the largest forest area in the region, the Hambach Forest, was largely cleared.
