What does this research mean for the field?

Surface horizontal displacement caused by underground mining is driven by a dual mechanism of rotational and translational displacement, and integrating these mechanisms into a novel R&T model significantly improves prediction accuracy over existing probability integral models. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To determine the fundamental mechanisms causing surface horizontal displacement during underground mining and develop a more accurate predictive deformation model.

Implication

Simulation and modeling study reveals dual rotational and translational ground displacement mechanisms during underground mining, improving surface hazard prediction accuracy over standard models.

Key Points

To determine the fundamental mechanisms causing surface horizontal displacement during underground mining and develop a more accurate predictive deformation model.
Conducted numerical simulations to investigate overburden deformation patterns and horizontal ground movement mechanisms.
Formulated the R&T model combining boundary rotational displacement and central "Z"-shaped translational displacement.
Evaluated model accuracy against the probability integral model (PIM) and improved PIM (IPIM) using data from 4 engineering cases.
Identified two distinct horizontal displacement drivers: rotational displacement at the goaf boundary linked to surface tilt, and central translational displacement governed by a "Z"-shaped movement pattern resembling ground subsidence.
The R&T model achieved a relative root mean square error (RMSE) below 15% across 4 engineering cases, markedly outperforming the PIM (69.7%) and IPIM (53.8%).
