Description
Zhangyin Dai and five co-authors measure how mining and water weaken sandstone in a 2024 paper. In Guizhou, landslides tied to mining and rain are frequent, and the hard sliding rock is often sandstone. Knowing how the rock decays under both stresses helps predict slope failures.
Tests tracked water uptake, swelling, and strength loss after mining stress and wet-dry cycles. Mining raised water absorption slightly and swelling by a small margin as well. Strength dropped by several percent after mining action alone. Repeated wetting and drying steadily broke the rock down further. The combined decay rates feed safety models for mines and slopes in rainy regions. Engineers can use them to set inspection and drainage priorities.
