Description
Jie Yuan, Guangwei Liu, and Senlin Chai set out, in a 2024 paper, a method for building detailed 3D geological models of faulted slopes in open-pit coal mines. Mine staff need models that stay accurate as digging changes the ground. Their method combines digital elevation models with a half-edge boundary representation, which tracks the edges and faces of solids.
The steps start with borehole and section data to divide the rock into layers, guided by the geological history of the area. A weighted estimation rule fills the gaps, and a triangular mesh forms each layer surface. Fault surfaces are reshaped by morphing, which improves accuracy when data are sparse. Rules then handle the cuts where faults cross other faults or layers. Finally, updating steps keep the surface and the deep model in step. A real mine slope in China served as the test case.
