Ultrasonic Time-Frequency Response Characteristics for Damage Evolution of Back-Filling Concrete under Staged Loading Conditions
Under the influence of repeated mining disturbance, the back-filling body for the gob-side entry retaining may experience a reduction in the bearing capacity or even failure, complicating the control of surrounding rock stability in coal mines. This study employs an electro-hydraulic three-axis serv...
