Application Summary AI generated

This standard specifies the test method for measuring the swelling stress of rock, which is the pressure generated when a rock sample absorbs water and expands under confined conditions. It is primarily applied in the mining and geotechnical engineering industries to evaluate the stability of underground excavations, such as coal mine roadways and tunnels, where water-sensitive rocks may cause floor heave or support failure. The method is used in laboratory testing contexts to provide data for designing support systems and predicting ground behavior in water-bearing rock formations.
