Sensitivity Analysis of Coal-Pillar Loading and Roadway Floor Heave in High-Intensity Longwall Mining: Implications for Pressure-Relief Design

Severe floor heave in gate roadways under high-intensity longwall mining is primarily controlled by mining-induced stress redistribution. Abutment pressure is preferentially transferred through the coal pillar into the floor, accelerating floor ...
