煤和岩石物理力学性质测定方法 第3部分：煤和岩石块体密度测定方法
Application Summary AI generated
This standard specifies the test methods for measuring the block density of coal and rock samples, including the wax-sealing method and the direct measurement method. It is applied in the mining and geotechnical engineering industries to determine the density of irregular coal and rock specimens for resource evaluation, mine design, and stability analysis. The standard ensures consistent density data for calculating porosity, stress distribution, and reserves in underground and open-pit mining operations.
