In order to study the dynamic response and stability of goaf group under blasting stress disturbance, based on the structural characteristics of goaf group and its interaction with surrounding rock, the dynamic response model of goaf group was constructed, the dynamic response analysis method was created, the dynamic instability criterion was put forward, and its stability was judged. An underground limestone mine was selected as the object for calculation and analysis, which was compared with the results of numerical simulation and field monitoring. The influence of different blasting frequency, span-height ratio of goaf and height-width ratio of pillar on the dynamic response of goaf group was studied. The results show that under the disturbance of blasting stress, the calculation results of dynamic response analysis method are consistent with those of numerical simulation and field monitoring. The velocity and displacement response of the goaf group are mainly concentrated in the x and y directions. The blasting frequency significantly affects the velocity and displacement response of the goaf group, and the relationship curve between the two types of peak and frequency is " single peak ". The peak velocity increases first and then decreases with the increase of the span-height ratio of goaf, the inflection points of the peak velocity curves in the x and y directions are 0.8 and 0.6, respectively. The peak displacement increases linearly with the increase of the span-height ratio of goaf, and the linear change slopes in the x and y directions are 0.926 and 0.670, respectively. The peak values of velocity and displacement increase slowly with the increase of height-width ratio of pillar, which has a weak influence on the stability of goaf group. The research results can provide a new method for the dynamic response of goaf group.

为研究爆破应力扰动下采空区群的动力响应及其稳定性问题，基于采空区群的结构特征及其与围岩的相互作用，构建采空区群动力响应模型，创建动力响应分析方法，提出动力失稳判据，并研判其稳定性。以某地下石灰岩矿为对象进行计算分析，与数值模拟及现场监测结果对比验证，并研究不同爆破频率、空区跨高比及矿柱高宽比对采空区群动力响应的影响规律。结果表明：在爆破应力扰动下，动力响应分析方法计算结果与数值模拟、现场监测结果趋于一致；采空区群速度、位移响应主要集中在x与y方向；爆破频率显著影响采空区群速度、位移响应，两类峰值与频率关系曲线呈“单峰”状特征；速度峰值随空区跨高比增大呈先增后减变化，x与y方向速度峰值曲线拐点分别为0.8与0.6；位移峰值随空区跨高比增大呈线性增长，x与y方向线性变化斜率分别为0.926与0.670；速度、位移峰值随矿柱高宽比增大呈负指数缓慢增长，对采空区群稳定性影响较弱。研究成果可为采空区群动力响应问题提供新方法。
