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: …
Road extraction in open-pit mine is one of the important tasks of intelligent dispatching and manless driving.

Designed to allow haul road widths to be optimised, providing an engineered level of safety significantly better than a traditional rock bund. Consisting of a series of filled polyethylene shells which secure together in a row along the edge of an open pit road, the Edge Protector wall acts to support a bund of loose rock giving a vertical face ...
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 ...
For instance, in the context of open-pit molybdenum mine road extraction, Gu et al. (2021) reported an mIoU of 0.6941 and an mAcc of 0.8047. Another study on the same mine by Gu et al. (2022) recorded an mIoU of 0.7834 and an mAcc of 0.9408.
Pit haul roads are roads that are used by haul trucks and other mine traffic in and around pit areas including, in pit haul roads and ramps, bench roads, dump roads and ramps, etc. Roadway . The part of a road intended for vehicles, in contrast to the pavement or verge. Delineator . Markers erected to define the edge of the running surface of a ...
These options include fitting of curves to haul road centrelines, expanding centre lines to the required road widths, applying grades.
The road layout in open-pit mines was optimized by using raster-based least-cost path analysis, and the resulting zigzag road sections were simplified by applying the Douglas-Peucker algorithm.

High-precision 3-D road networks in open-pit mines (OPMs) play a crucial role in production planning, truck dispatching, and unmanned driving. Compared with urban road networks, the boundaries of OPM roads are indistinct, with varying widths. The colors of these roads blend with the surrounding environments and they undergo rapid changes. Thus, …
