摘要物理相似模拟是研究冲击地压问题的重要方法之一，其相似材料的合理选型是巷道或采场采掘扰动响应过程有效模拟的重要前提。因此，通过相似理论与数值模拟方法综合研究冲击地压物理相似模拟中不同冲击倾向性原型煤和相似煤材料的破坏特征及几何相似比关联性，推导获得基本参数、阻尼、能量及冲击倾向性指标的相似条件，基于此借助连续–非连续模拟方法开展不同冲击倾向性煤的煤样和煤巷模型冲击破坏特征几何相似比关联性研究。研究结果表明：强冲击倾向性煤样呈弹脆性冲击破坏，无冲击倾向性煤样峰后为应变软化形式的静态破裂；对于几何相似比分别为2，5，10，20的煤样相似模型，其单轴抗压强度模拟值与理论值基本一致，冲击能量指数随几何相似比增大先减小再趋稳，煤样的碎裂程度和碎屑动能均随几何相似比增大而下降；强冲击倾向性煤体的原型煤巷开挖有动态破坏过程，且随着几何相似比增大，巷帮煤体动能逐渐减小，煤巷由动态破坏最终转变为静态破坏。最后，讨论物理相似模拟中动力破坏行为的几何相似比关联性原因并给出冲击地压物理相似模拟材料选型及冲击现象模拟条件的一些建议。研究对开展冲击地压物理相似模拟研究具有指导意义。

Abstract：Physical similarity simulation is one of the important methods for studying coal/rock burst problems，and the rational selection of similar materials is a crucial prerequisite to ensure the effective simulation of mining disturbance response of roadway or longwall working face. Therefore，through the comprehensive study of similarity theory and numerical simulation methods，the fracturing characteristics as well as the effect of geometric similarity ratio of different bursting-prone prototype coals and similar coal materials in physical similarity simulation of coal/rock burst were investigated. The similarity conditions for basic parameters，damping，energy and bursting liability indexes were obtained，and the geometric similarity ratio correlation of coal/rock burst failure characteristics of coal samples and coal roadway models with different coal bursting liabilities was studied using the continuous-discontinuous simulation method. The results show that the coal samples with strong bursting liability exhibit elasto-brittle dynamic failure，while those without bursting liability represent static rupture in forms of post-peak strain-softening. For the coal sample similarity model with geometric similarity ratios of 2，5，10 and 20，the simulated values of uniaxial compressive strength are basically consistent with the theoretical values. The bursting energy index decreases first and then stabilizes with the increase of geometric similarity ratio，and the fragmentation degree and debris kinetic energy of coal samples decrease with the increase of geometric similarity ratio. The excavation of prototype coal roadways with strong bursting liability reveals a dynamic failure process，and the kinetic energy of the coal ribs decreases gradually with increasing geometric similarity ratio，and the roadway eventually transforms from dynamic failure into static failure. Finally，the reasons for the correlation of geometric similarity ratio in the dynamic failure behavior of the physical similarity simulation are discussed，and some suggestions are given for the selection of materials for the physical similarity simulation of coal/rock burst and the simulation conditions of burst phenomena. This study provides guidance for the physical similarity simulation of coal/rock burst.
