Examine the factors influencing the height of water-conducting fracture zones across different coal seams.
Analyzed 147 WCFZ height samples from Carboniferous-Permian seams and 111 from Jurassic seams.
Constructed a Bayesian-optimized random forest regression model (BO-RFR) for height prediction.
Assessed individual factor contributions using SHAP analysis.
Identified the ranking of factors influencing WCFZ height for each coal seam type.
Showed superior predictive capability of the BO-RFR model for estimating WCFZ heights.
Provided guidance for safety assessment in coal mining regions.
