Comparison with Existing Studies.

<div><p>Rock defects are a key internal factor leading to deformation and failure under load. This study investigates red sandstone specimens with combined pore–fracture defects at different pore dip angles through uniaxial compression tests, while employing Acoustic Emission monitoring...
