Construction of a 3D visualization model of an open-pit mine production operation scenario in the context of sustainable development

The rapid increase in the production capacity of open-pit coal mines has resulted in the development of mining and transportation equipment that is large-scale, serialized, safe, efficient, green, and sustainable. This has led to higher requirements for the refined modeling of mining production scenarios. Nevertheless, the intricate nature of open-pit mines makes modeling more challenging. This study presents a comprehensive investigation and analysis of the operational environment of open-pit coal mines. The contour lines and bench lines of the mining and stripping project plan view are selected as the data source for modeling and construction of a grid DEM of the open-pit coal mine production scenario. The grid is interpolated to obtain the point elevation values, and a constrained triangulated irregular network (TIN) is constructed using the top and bottom lines of the bench slope as constraints. The 3DS Max software is employed to construct the open-pit coal mine production and operation scene model, which is then imported into the Unity3D virtual engine development platform for rendering optimization. The findings of this study offer novel insights into the modeling of open-pit coal mine production and operation scenes and provide robust support for the sustainable development of open-pit mines.
