Fracture behavior and acoustic emission characteristics of sandstone samples with inclined precracks
Abstract Sandstone samples with precracks of different dip angles were collected from a coal mine roof and subjected to uniaxial compression tests, and acoustic emission (AE) and scanning electron microscopy (SEM) were used to study how the crack dip angle affected the fracture mechanism. In the pre...
