Application Summary AI generated
This standard specifies laboratory test procedures for measuring the water absorption rate and water absorption capacity of coal and rock samples under atmospheric pressure. It is applied in the mining and geotechnical engineering industries to evaluate the water sensitivity of coal seams and surrounding rock, which is critical for predicting roof stability, preventing coal and gas outbursts, and designing water-based dust suppression systems.
