Aiming at the problem that the impact vibration caused by roof caving threatens the stability of stope in caving mining, a physical simulation experiment was designed based on the mechanism of caving impact vibration and the similarity law of physical simulation. The relationship between the caving impact vibration velocity and the falling height of the caving body, the amount of one caving, the porosity of the cushion, the thickness of the cushion and the distance of the measuring point was systematically studied. The results show that the caving impact vibration velocity is positively correlated with the falling height of the caving body and the amount of one caving, and negatively correlated with the thickness of the cushion and the distance of the measuring point. With the increase of the porosity of the cushion, the caving impact vibration velocity decreases first and then increases. The correlation between the caving impact vibration velocity and each factor from high to low is the distance of the measuring point, the amount of one caving, the falling height of the caving body, the thickness of the cushion, and the porosity of the cushion. Based on the test results and the calculation method of blasting vibration velocity, an empirical formula for calculating the caving impact vibration velocity was constructed and applied to the west No.2 mining area of Jinchuan Longshou Mine. The maximum vibration velocities of roof caving at 1 595 m, 1 554 m and 1 494 m are 6.4 cm/s, 3.7 cm/s and 3.0 cm/s, respectively. The maximum vibration velocities measured in the field are 1.21 cm/s, 0.26 cm/s and 0.09 cm/s, respectively, which verifies the reliability of the measurement method. The research results can provide theoretical basis and practical guidance for the prevention and control of roof caving impact disasters in underground mines.

针对崩落法开采中顶板冒落所引起的冲击振动威胁采场稳定的难题，基于冒落冲击振动机理及物理模拟相似定律设计物理模拟试验，系统研究了冒落冲击振动速度与冒落体下落高度、一次冒落量、缓冲垫层孔隙率、缓冲垫层厚度、测点距离等五个因素的关系。结果表明：冒落冲击振速与冒落体下落高度、一次冒落量呈正相关，与缓冲垫层厚度、测点距离呈负相关，随缓冲垫层孔隙率增大呈先下降后上升的变化规律；冒落冲击振速与各因素相关程度由高到低依次为测点距离、一次冒落量、冒落体下落高度、垫层厚度、垫层孔隙率。基于试验结果及爆破振速计算方法，构建了冒落冲击振速测算经验公式，并将其应用于金川龙首矿西二采区。测算得出崩落法采场顶板冒落在1 595 m、1 554 m及1 494 m所能产生的最大振速分别为6.4 cm/s、3.7 cm/s、3.0 cm/s，现场实测值最大振速分别为1.21 cm/s、0.26 cm/s、0.09 cm/s，验证了测算方法的可靠性。研究结果可为地下矿山顶板冒落冲击灾害预防和控制提供理论依据和实践指导。
