To evaluate and predict the structural stability of vertical mine shafts situated beneath thick, loose aquifers impacted by coal seam mining.
Analyzed structural parameters and monitoring data collected from 15 damaged coal mine shafts located in East China.
Constructed an evaluation framework combining the comprehensive weight method with a fuzzy matter-element analysis model.
Identified surface subsidence velocity and water level drop at the bottom of loose aquifers as the two primary factors influencing shaft stability.
Achieved a predictive accuracy of 86.67%, with model classifications matching actual production outcomes in 13 out of 15 sample shafts.
