“…When discussing road width design, it is important to note that this paper differs from other studies in that optimizing road widths for open-pit mines can be economically beneficial, while optimizing urban road widths can be costly. Chen et al focused on how the optimal balance between vehicle lane widths and pavement widths on roads in urban areas can minimize the safety and construction costs [26]. The research incorporated both safety costs and agency costs to determine the optimal road space allocation and evaluated how different weightings of these costs impact the optimal allocation of lane and footpath widths.…”

In an effort to enhance the efficiency and safety of open-pit mines, this study explores the optimization of end slope road parameters and slope structures, specifically focusing on unmanned driving lanes. A significant aspect of the study is the development of a truck trajectory offset model, which considers the different reaction times between automated sensors and human drivers in adapting to environmental changes. To test these concepts, the study uses numerical simulations to confirm the stability of the proposed end slope designs. Using Victory West Mine No. 1 as a case study, the research determines the optimized width for unmanned driving lanes and the maximum angle for the safe steepening of end slopes. The findings indicate that the optimized unmanned lane width for NTE240 mining dump trucks is 1743 mm, allowing for a 2-degree increase in the slope angle at the south end slope. This optimization leads to a steep mining stripping volume of 3.2735 million m3 and a coal output of 2.49628 million tons, maintaining a stripping ratio of 1.31 m3/t. These results demonstrate that unmanned driving road width optimization not only ensures slope safety but also significantly boosts the economic benefits of steep mining in open-pit mines.
