Abstract: In order to solve the problem of over excavation and poor surrounding shaping effect during the drilling and blasting of the rock roadway in Fangezhuang Mine, through indoor experiments, the physical and mechanical parameters of the surrounding rock were determined, and the HJC constitutive model parameters were calibrated. Through numerical simulation, the crack propagation laws of the rock under the action of ordinary explosives, slotted cartridge, 90°, 180°, and 270° protective wall casings were compared. The application effects of different control blasting techniques on peripheral eyes were compared through engineering experiments. The numerical simulation results show that the slotted cartridge can achieve directional fracture blasting well in the cutting seam direction, and the crack length in the non cutting seam direction is reduced by 56.71%. The curvature of the protective casing has a significant impact on the distribution of crushing zone and radial cracks. The crack length on the protective wall side of the 90° and 180° protective sleeves is decreased by 79.9% and 75.1%. The average length of cracks on the protective wall side of the 270° protective sleeve is decreased by 58.57%. The explosion load caused more damage to the rocks on the side of goaf. The engineering test results show that both the slotted cartridge and the protective wall casing can play a role in directional control blasting to a certain extent. Compared with ordinary explosives, the use of slotted cartridge reduces the amount of average over excavation by 158.33 mm. The average over excavation amount corresponding to the three types of curved wall protection sleeves is reduced by 63 mm, 125.67 mm, and 224.67 mm. The half eye mark rate increases with the curvature of the protective wall sleeve, and adjusting the curvature of the protective wall sleeve can improve the forming effect of the peripheral eyes.
