Study on Acoustic Emission Response and Failure Characteristics of Rock–Proppant–Rock Composite Constructions Under Uniaxial Compression
To reveal the bearing and instability mechanisms after filling proppants in the blasting pressure-relief fracture, four types of proppant-containing sandstone composite construction with interface inclinations of 0°, 4°, 8°, and 12° were prepared. A uniaxial compression test was conducted by combining Acoustic Emission...
