| 英文摘要 | The co-development of saline aquifers and coal seams in sedimentary basins results in geomechanical conflicts when concurrently exploited in shared subsurface strata. However, reliable assessments of CO2 storage effects on coal mines are limited by uncertainties associated with the mechanical and physical characteristics of deep rock formations. Studies have developed advanced hydraulic-mechanical (HM) coupling frameworks for CO2 storage in saline aquifers or coal seams; however, no study has quantitatively linked parameter uncertainties to coal mine stability thresholds under CO2 injection pressures, a gap addressed in this study. This study investigated the critical parameters governing coal mine stability under CO2 injection at the Shenhua CCS site. A coupled MRSTFLAC3D model was developed to simulate HM interactions, and Tornado analysis and response surface methodology were performed to evaluate 17 parameters, with F-values quantifying their significance. Predictive models for CO2 plume radius (R) and vertical displacement (U) were established, revealing three key findings: (1) reservoir porosity had the dominant effect on R variations (73.6), exceeding the influences of reservoir permeability (34.16) and reservoir thickness (0.95) by orders of magnitude; (2) U was most sensitive to the caprock Poisson's ratio (1, 240.22), followed by the caprock Young's modulus (1, 019.59), Biot's coefficient (707.8), interbedded mudstone-sandstone Poisson's ratio (367.22), and reservoir permeability (289.45); (3) the R and U models robustly predicted CO2 migration and stratum deformation across diverse geological conditions. These findings provide a quantitative framework for optimizing CO2 storage integrity and coal mine safety in tectonically active basins, with implications for global CCS projects facing similar resource conflicts. |
