In order to study the dynamic response characteristics of adjacent roadway under blasting action, taking the adjacent roadway of a mine as the engineering background, the 3DEC discrete element simulation software was used to establish a bonded block model considering the discontinuous characteristics of rock mass. The vibration velocity field, stress wave propagation and fracture evolution law of surrounding rock of adjacent roadway under blasting load were simulated, and the response characteristics of the surrounding rock under different blasting rising time was analyzed. The results show that the short rising time makes the energy of blasting wave release intensively, which leads to the high peak vibration velocity of surrounding rock particles, but the attenuation is rapid. The long rising time makes the energy distribution more uniform, but the peak vibration velocity of surrounding rock particles decreases significantly, and the cumulative damage to surrounding rock is more significant. The evolution of fracture fractal dimension presents two-stage characteristics, which increases sharply in the early stage of blasting and increases slowly in the later stage. The long rising time has a stronger promoting effect on the expansion of surrounding rock damage range. Based on the stress wave propagation and the distribution law of the peak particle velocity of the surrounding rock, the short rising time is suitable for efficient blasting scenarios, while the long rising time needs to be combined with charge control to reduce the damage of the surrounding rock. The research results provide a theoretical basis for the safety design and construction control of blasting excavation in adjacent roadways.

为研究爆破作用对邻近巷道的动态响应特征,以某矿山邻近巷道为工程背景,采用3DEC离散元仿真软件,建立考虑岩体非连续特性的黏结块体模型,模拟爆破载荷作用下邻近巷道围岩的振动速度场、应力波传播及裂隙演化规律,分析不同爆破上升时间下的围岩响应特征。结果表明:短上升时间使爆破波能量集中释放,导致围岩质点峰值振速较高,但衰减迅速,而长上升时间使爆破波能量分布更均匀,但围岩质点峰值振速显著减小,对围岩的累积损伤更显著;裂隙分形维数演化呈现两阶段特征,爆破初期急剧增加,后期缓慢增长,长上升时间对围岩损伤范围扩展的促进作用更强;基于应力波传播与围岩质点峰值振速分布规律,短上升时间适用于高效爆破场景,而长上升时间需配合装药控制以减少围岩损伤。研究成果为邻近巷道爆破开挖的安全设计与施工控制提供了理论依据。
