Abstract: In order to improve the mining efficiency and ensure the blasting safety of limestone mine, the bench blasting scheme and its parameters of hole network are designed based on theoretical analysis and field experience, taking a limestone mine in Sichuan Province as the research background. At the same time, the blasting effect is analysed and evaluated by the safety allowable distance of blasting vibration, blasting flying stone, blasting shock wave and blasting noise. The research results show that the safety allowable distance of blasting vibration is 30.0 m for 120 mm blasthole. The safety allowable distance of blasting shock wave is about 193 m, and the safety allowable distance of blasting noise is about 196.9 m. Compared with simultaneous initiation, millisecond delayed initiation can effectively reduce the generation of blasting flying stones. In order to avoid flying stone due to too large of delay time, as well as crack of rock, the delay time is calculated and determined as 40 ms between with each blasthole. In addition, presplitting blasting can greatly reduce the damage of blasting vibration to the slope of open-pit mine. The scheme and parameters of presplitting blasting are designed, the presplitting holes are initiated before the main holes for 150 ms. The normal direction of the free surface of the blasting bench should deviate from the direction of the road and the house, or parallel to the direction of the road and the village, which can effectively protect the nearby structures. Non-blasting mining should lag behind blasting mining to provide safe shelter for blasting mining. The research results provide some guidance for the design and construction of bench blasting.
