Slope stability analysis forms an integral part of the opencast mining operations during the life cycle of the project. In Indian mining conditions, slope design guidelines are yet to be formulated for different types of mining practices and there is a growing need to develop such guidelines for maintaining safety and productivity.
Learn how mining engineers deal with the risks and uncertainties of exploration and development projects, from geological to social factors.
The pilot mine stage of a mining project may also be considered phase one production — or the first step on the path to full-scale production. Unlike bench-scale testing in the lab, a pilot-scale mine allows the company to study the proposed process under the same conditions as will exist in the full-scale mill without the cost of ...

One of the most challenging problems geologist and engineer encountering in open pit mining is how much ore at benches can be extracted and sent to mill at the same time. Cutoff grade is playing an important role in solving this problem. The author, in this paper, presented a hauling cost-bench model, which directly impact cutoff grade. The cost model indicates that hauling …
The mining industry contributes significantly to the health of the worlds' economy. Indeed, the total annual revenue generated by the industry worldwide has exceeded $500 billion US for the past 6 years. ... to help in analysis of potential benefits of envisaged modifications concerning an existing truck type and/or development of a new type ...
Bench is a horizontal layer of ore rock upon which stripping and mining are performed in an open-pit mine. The bench is an essential constituent of the open stope. The …
The project will be developed in two phases. Phase 1 involves the development of an 86 000 t/y run-of-mine operation producing 1 760 t/y of concentrate for shipment to a planned refinery, in Lilongwe.

the bench geometry defines the steepest interramp slope that can be mined while maintaining adequate catch bench widths. The two primary factors that control bench configuration are the type of mining equipment that is used and the bench face angles that can be achieved. The type of mining equipment determines the
Proper mining sequence is critical to viable development of an open-pit mine. It determines the volume of cash and the time the cash will begin to flow into the project.
The article is aimed at improving development mining to prepare an ore body for stoping by access ramps to provide comfortable conditions and high technical and economic indices in underground mining.

quality routines. As a consequence, catch benches were too narrow and the design criterion for these was not fulfilled. These findings motivated a more extensive project on smooth blasting, as described below. 2.2 Blasting trials An extensive project on smooth blasting was conducted in the period of 1991 to 1996. The project was
For a bench stack angle that satisfies the stability criteria, various combinations of bench height, bench face angle and berm width can be used in the slope design.
