Abstract: Investigating the pressure relief control characteristics of advance roadway sections is key to optimizing pressure relief parameters in high-stress roadways. Taking the mining disturbance of high-stress roadways in a mineas the research background, the continuous-discrete element method （FDEM） is employed to study the regulatory effects of pressure relief parameters on the distribution of advance abutment pressure. Increasing borehole diameter and reducing borehole spacing can decrease the peak abutment pressure. When the hole diameter increases from 180 mm to 210 mm, the peak pressure reduction reaches 4.82%; when the hole spacing decreases from 3.0 m to 1.5 m, the peak pressure is reduced by 5.76%. During mining, the abutment pressure shifts forward and exhibits a secondary peak after 30 m of extraction. High crack density near the working face causes borehole collapse in pressure relief holes, weakening their effectiveness; while intact pressure relief hole structures maintain sustained pressure relief effects in distant areas. Field monitoring confirms that the optimized pressure relief boreholes can effectively reduce surrounding rock stress and maintain efficient pressure relief. During coal face mining, dynamically adjusting pressure relief parameters based on the evolution of surrounding rock stress and promptly implementing secondary hole enlargement measures can effectively reduce advanced abutment pressure and ensure sustained pressure relief effectiveness.
