Roots can effectively consolidate and support the soil and are affected by external forces. To identify the survival strategies and soil reinforcement capability of roots against damaging forces, we investigated Hippophae rhamnoides taproots with a diameter of 1-4 mm in a coal mining subsidence area. To simulate root damage from erosion, an HG100 digital push&pull tester and self-developed ...
