Optimization of cross-sectional shape and support parameters of headgate in fully mechanized coal seam with large dip angle and close distance

Optimization of cross-sectional shape and support parameters of headgate in fully mechanized coal seam with large dip angle and close distance

Aiming at the problem that the asymmetric deformation and failure of surrounding rock frequently occur, making it difficult to control the surrounding rock under the conditions of multiple intense mining actions in thecoal seam with large dip angle and close distance. Taking the headgate 31233 in Da...
