Scope

Scope: This standard specifies the instrumentation and equipment, specification of test pieces, temperature of the test environment, test procedures, calculation of results, and test record forms for uniaxial compression creep tests on coal and rocks under dynamic disturbance. This standard is applicable to the testing and calculation of the creep performance of coal and rocks under dynamic disturbance. Main technical content: 1. Instrumentation and equipment 2. Specification of test pieces and temperature of the test environment 3. Test procedures: - Test on the influence of dynamic disturbance on the creep performance of test pieces under constant load; - Test on the influence of dynamic disturbance on the creep performance of test pieces under gradual loading. 4. Calculation: - Calculation of axial strain and radial strain; - Stress calculation; - Calculation results
