This standard applies to the calculation of porosity of coal and rock, including the determination of total porosity and effective porosity. The standard specifies the terms, definitions and methods for the calculation of porosity of coal and rock, and is suitable for specimens that do not collapse and are stable in volume. Through accurate measurement of porosity, it provides necessary technical support for coal mining and geological engineering, ensuring the safety of engineering activities and the accuracy of material characteristic analysis.
