comparison between open-pit ramp designs obtained …

The problem of strategic open pit planning involves several stages, including (1) ultimate pit, (2) pushback ... Moreover, switchbacks cause greater tire wear and various road maintenance problems. Further, there are other parameters related to the geometric design that require additional work for the planner, such as the slope of ramps, the ...

Selection of practical bench height in open pit mining …

Every bench in open pit mines composes a slope which its stability should be guaranteed to ensure safety of the entire pit. Today, the factor of safety is the most common measure of slope stability, and there is wide experience in its application to all types of geological conditions (Wyllie and Mah, 2005). For open pit mines, the factor of

A road extraction method for intelligent dispatching based …

Road extraction in open-pit mine is one of the important tasks of intelligent dispatching and manless driving. However, traditional methods for extracting open-pit roads cannot capture detailed information about roads, such as shape and surrounding environment. An MD-LinkNeSt (Multi Dilation-LinkNeSt) network is proposed to extract the open-pit ...

A New Method for Haul Road Design in Open-Pit Mines to …

The design of a haul road for an open-pit mine can significantly affect the cost associated with hauling ore and waste to the surface. This study proposes a new method for haul road design in open-pit mines to support efficient truck haulage operations. The road layout in open-pit mines was optimized by using raster-based least-cost path analysis, and the resulting …

Optimum ramp design in open pit mines

Because in-pit ramps require the removal of a considerable amount of non-valuable material (stripping), we discuss two different problems: high stripping (or in-pit) ramp design and low stripping (or ex-pit) road design. For the first situation, we present an integer programming model; in the second case, a shortest path approach is undertaken.

The safest way to increase overall pitwall slope

Decreasing haul road widths throughout an open pit mine will increase overall pit slope without changing the inter-ramp slope angle and impacting the slope stability. Steepening the pit slope will have both environmental and economic impacts. Increasing the pit slope will determine the stripping ratio as well as

Optimum ramp design in open pit mines

The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational costs. Because in-pit ramps require the removal of a considerable amount of non-valuable material (stripping), we discuss two different problems: …
