Underground coal mine reservoirs experience repeated impoundment and drainage, exposing coal pillars to dry–wet cycling and causing cumulative deterioration. This study investigated the acoustic and mechanical responses of Wudong coal specimens subjected to 0, 1, 3, and 5 dry–wet cycles through mass measurements, P-w...

Accurate, comprehensive, and spatially continuous monitoring of mining-induced surface subsidence is essential for geohazard prevention, ecological restoration, and safe mining. Conventional approaches, however, are limited by the sparse spatial distribution of GNSS observations, the difficulty of InSAR in resolving la...
