Abutment Pressure of Main Roadway Coal Pillars in Close-Distance Seam Mining Considering Stress Superposition
In close-distance coal seam mining, the stability of main roadway pillars is critically influenced by stress superposition from overlying remnant pillars. This study develops a theoretical model that integrates elastic foundation beam theory with the Boussinesq solution to evaluate the abutment pressure of the lower co...
