Open pit mining is a technique used to extract copper ore near the earth''s surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth''s surface.
Openpit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.
Apr 05, 2013· The project involves the surface mining, via what appears to be an open pit method, of a sandstone geologic formation that includes hardened asphalt, or bitumen, which is heavy oil–the same type found in the Canadian tar sands. The mine location .
Bitumen can be extracted using two methods depending on how deep the deposits are below the surface: insitu production or open pit mining. Insitu Production. Insitu extraction methods are used to recover bitumen that lies too deep beneath the surface for mining .
Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.
Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are ...

planning and design processes employed by surface mining oil sands operations vary in distinct ways from other commodities mined by both hard and soft rock open pit methods. The unique waste handling needs, including tailings disposal, of contemporary oil sands mining .
– Openpitmining if the deposit is on the surface – Insitu or drilling if the deposit is stocked underground as conventional crude. The method is selected in respect with the depth of the reserves. In Canada about 3% of the 140,000 square kilometers of land contain mineable deposit, the other 97% will require the insitu approach.
There are two primary extraction methods for oil sands: openpit mining and insitu mining. The technique used depends on the depth of the deposit. For example, insitu mining is used when bitumen lies too deep beneath the surface for openpit mining. Injection of steam is used in both methods to heat the bitumen, which serves to make it more ...
OpenPit Mining. Openpit mining, or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining.

There are two different methods of producing oil from oilsands: openpit mining and in situ (latin, meaning "in place") technology. Bitumen close to the surface is mined. Bitumen deep within the ground is produced in situ using specialized extraction techniques.
mining: Openpit mining Deposits mined by openpit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it.

Jan 07, 2016· The insitu method will account for 80% of the total bitumen collected and open pit mining will only retrieve 20%. The open pit mining method requires large scale excavation of the land with huge hydraulic power shovels and 400ton heavy hauler trucks.
Openpit mining – if tar sands are found near the surface, as in Alberta, Canada, they can be mined directly – much like openpit coal mining – and then transferred to an extraction plant where the bitumen can be separated from the sand, clay, and water.
Rubbermodified bitumen materials for openpit enterprises ... has belonged to openpit mining, which is the most ... and safest method. The scale of openpit mining is increasing, both through an increased intensity of work at quarries and through the development of fields lying at depths of 300 m or more. As a result of this, there has been ...
Through the use of a range of geochemical techniques, this work quantitatively and qualitatively investigated the effect of openpit coal mining operations on rice paddy soils and rice plants ...
Only 20 percent of bitumen can be extracted using open pit mining methods, which involves large scale excavation of the land with huge hydraulic power shovels and 400ton heavy hauler trucks. Surface mining leaves toxic tailings ponds. In contrast, in situ uses more specialized techniques such as steamassisted gravity drainage (SAGD).
There are two different methods of producing oil from oil sands: openpit mining and in situ. Bitumen that is close to the surface (less than 75 metres) is mined. Approximately 20% of oil sands are recoverable through openpit mining.
The viscous nature with the combination of clay, sand, water and bitumen makes mining of the tar sands difficult. Deposits of tar sand near the surface can be extracted by openpit mining.
There are two different methods of producing oil from oil sands: openpit mining and in situ. Bitumen that is close to the surface (less than 75 metres) is mined. Approximately 20% of oil sands are recoverable through openpit mining.
Open pit mining is only practical for bitumen deposits that exist near the surface. These deposits are mined and moved by trucks to a cleaning facility where the bitumen is extracted from the sand. For oil sands beneath the surface, however, thermal recovery methods (often called " in situ " methods.
