In order to reveal the deformation and failure laws of surrounding rock in jointed roadway under dynamic load, 3DEC software was used to simulate and analyze the influences of different burial depths, peak stresses, and load frequencies on the deformation and instability characteristics of surrounding rock in jointed roadway under blasting load in a certain mine. The results show that with the increase of blasting load disturbance time, the displacement of the roof, floor, and right wall of jointed roadway firstly increases, then decreases, and finally stabilizes. The displacement of the roadway surrounding rock increases linearly with the increase of burial depth and peak stress, and the plastic zone area of the roadway surrounding rock also increases accordingly. The deformation and failure degree of the roadway surrounding rock deepen, and the most serious location is on the floor.The displacement of the roadway surrounding rock decreases linearly with the increase of load frequency, and the area of the plastic zone around the roadway slightly decreases. The influences of three factors on the deformation of roadway surrounding rock were analyzed by response surface methodology. It was found that the burial depth had the most significant impact, followed by the peak stress, and the load frequency was the smallest. The research results can provide a theoretical guidance for mine safety production.

为了揭示动载作用下节理化巷道围岩变形破坏规律,采用3DEC软件模拟分析了某矿山爆破荷载作用下不同埋深、应力波峰值和荷载频率对节理化巷道围岩变形及失稳破坏特征的影响规律。结果表明:随着爆破荷载扰动时间的增加,节理化巷道顶板、底板和右帮位移均先增大后减小最后趋于稳定;巷道围岩位移随埋深与应力波峰值的增加呈线性增加的趋势,巷道围岩塑性区面积也随之增加,巷道围岩变形和破坏程度加深,巷道底板的变形破坏最为严重;巷道围岩位移随荷载频率的增加呈线性减小的趋势,巷道周围的塑性区面积略有减少。通过响应面法分析了3个因素对巷道围岩变形的影响作用,发现埋深对巷道围岩变形影响最为显著,应力波峰值次之,荷载频率影响最小。研究成果可为矿山安全生产提供理论指导。
