Aiming at the practical problem of severe surrounding rock deformation and failure in the 183lower06 belt gateway of Jining No.3 Mine, the combined method of theoretical analysis, field measurement and engineering application was adopted in this paper. The essential causes for abnormal strata pressure behavior of the 183lower06 belt gateway were clarified. The key parameters of deep hole blasting roof cutting technology and large diameter borehole pressure relief were quantitatively calculated. A prevention control strategy of “deep hole blasting roof fracturing technology + large diameter borehole pressure relief” suitable for hard roofs was proposed. The pressure relief and hazard elimination effects were verified and evaluated by the drilling cutting method and stress monitoring method. The conclusions were drawn as follows: ① The strata pressure behavior of the belt gateway in No.183lower06 Face was divided into two stages: static load energy accumulation and dynamic load disturbance. Elastic energy was accumulated in the static load energy accumulation stage. Mine tremors were induced by roof fracture and caving in the dynamic load disturbance stage. The coupling of static and dynamic loads was resulted in severe roadway deformation, support instability and frequent high energy events. ② The deep hole blasting roof fracturing technology was mainly applied for the prevention and control of dynamic load disturbance. A borehole diameter of 80 mm and a borehole depth of 25 m were obtained through calculation. A roof cutting angle of 30° and a roof cutting height of 21 m were determined via mechanical derivation. ③ Artificial weakening zones were formed in the roof by large diameter borehole pressure relief, which was mainly used to release high static load stress in coal ribs. A borehole diameter of 150 mm, a borehole depth of 25 m and a borehole spacing of 800 mm were obtained through calculation. ④ The pressure relief and hazard elimination effects were evaluated and verified by combining the drilling cutting method and stress monitoring method. The drilling cutting quantity for deep hole blasting pressure relief was reduced by 58.3%, and the stress was stabilized at 5.0 MPa. The pressure relief performance was superior to that of borehole pressure relief. Surrounding rock deformation was effectively controlled. Theoretical basis and technical references were provided for roadway strata pressure control under similar complex geological conditions.
