Summary: | The article reports data on continuous indentation of different rank black coal and anthracite. The test specimens are specially prepared, and their faces are differently oriented relative to their bedding planes. Different mechanical behavior of coal and anthracite microcomponents in different planes relative to bedding is identified, and relevant values of elasticity modulus and hardness are determined. The measurements exhibit spatial anisotropy of microlevel mechanical properties of vitrinite and inertinite. |
