![]() ![]() Water-bearing coal was investigated under a coupled compression–shear load using inclined uniaxial compression tests on coal samples with varying water contents ( ω = 0%, 2.42%, 5.53%, 7.55%, and 10.08%) and acoustic emission (AE) technology. The moisture content and loading angle inclination significantly impact the strength and stability of the safety coal pillar of underground reservoirs. ![]() The construction of an underground coal mine reservoir plays an essential role in the ecological environment of arid areas.
