Study on deflection of principal stress and deformation characteristics of roadway surrounding rock under mining action in close-distance coal seams

AbstractThe traditional index to determine the width of the stopping coal pillar (WSCP) is generally only the front abutment pressure, but the direction of the principal stress will deflect due to the mining action, which brings significant challenges to controlling the surrounding rock. Based on th...
