underground mine 3d model

Create a huge realistic underground mine digital twin. Show a large surface terrain with clearly visible soil, rock strata, geological layers and a coal/mineral seam. Below it, create deep hollow tunnels, branching passages, large mining chambers, shafts, junctions and strong support pillars. Include a major subsidence depression with surface cracks directly above a damaged underground section. Add realistic roof collapse, broken pillars, fallen rocks, rubble and a rockslide zone. Add 8 separate sensor nodes labeled N1–N8 across surface and underground. Use detailed realistic geology, clean modular geometry and a clear cutaway view showing surface and mine together.
