As a multi-phase composite cement-based material, filling body is widely used in goaf filling. Therefore, the acoustic emission characteristics and material fracture evolution of the combined backfill with different cement-tailing ratios under compression were investigated via uniaxial compression acoustic emission (AE) tests to clarify the failure law of the backfill under the action of overburden. The results show that the proportion of tailings has an effect on the acoustic emission characteristics of the composite backfill. During the failure process, the acoustic emission characteristics of the composite backfill are dominated by cold joints and weak surfaces, and the stress is 79%-88% in the specimen. At the peak stress, the acoustic emission parameters show a downward trend. Before the stress peak, the AE energy fluctuates violently, and the b value increases steadily. After the stress peak, the AE energy decreases, and the b value increases rapidly and fluctuates violently. The evolution of acoustic emission parameters can be used to predict the damage of the backfill.
