Study on the Mine Pressure Behavior Regularity of Roadways When Passing Through Remaining Coal Pillars in Thick Seam Mining

Residual coal pillars retained in the overlying seam represent an important source of stress disturbance that can intensify mine pressure responses in underlying thick coal seam mining. Taking the downward mining of the Carboniferous–Permian dual-system extra-thick coal seam in the Xiao Coal Mine as the engineering con...
