To deeply understand the true triaxial mechanical characteristics of coal-rock combinations under mining disturbance, the octahedral shear stress theory was adopted to systematically study the true triaxial mechanical characteristics and energy evolution mechanism of coal-rock combinations affected by the interface inclination angle during mining disturbance. Finally, based on Drucker-Prager criterion, a true triaxial damage constitutive model for coal-rock combinations considering the influence of the interface inclination angle was established. The results show that during the excavation disturbance stage, the axial strain of the coal-rock combination increases linearly with time. The energy is mainly converted into elastic energy, and the dissipative energy gradually increases as the strain increases. When the interface inclination angle exceeds 60°, the shear stress increases significantly, and the node of shear stress increase is postponed to the end of the excavation stage. During the mining stage, the energy of the specimen is mainly used for deformation and failure. When the interface inclination angle is less than 60°, the specimen undergoes two deformations before the shear stress reaches the strength limit. At the end of the mining disturbance, there are two sudden increase nodes in strain, and then the shear stress drops sharply, with the proportion of dissipative energy approaching 1. When the interface inclination angle is greater than 60°, the peak value of axial strain decreases, the sudden increase node of strain is postponed and is synchronized with the sudden drop node of shear stress, and the deformation and failure of the combination mainly depend on the rock mass part. After model verification, the goodness of fit is higher than 90%.

为深入掌握采掘扰动下煤岩组合体真三轴力学特性,采用八面体剪应力理论,系统研究采掘扰动下受交界面倾角影响的煤岩组合体真三轴力学特性及能量演化机制,并最后基于德鲁克-普拉格准则,建立考虑交界面倾角影响的煤岩组合体真三轴损伤本构模型。结果表明:开挖扰动阶段,煤岩组合体轴向应变随时间线性增长,能量主要转化为弹性能,随着应变增大耗散能逐渐增加;当交界面倾角超过60°时,剪应力明显增大且增大节点延后至开挖末期。回采阶段,试样能量主要用于变形破坏;交界面倾角小于60°时,试样在剪应力达到强度极限前会发生2次变形,回采扰动末期应变有2个骤增节点,随后剪应力骤降,耗散能比例趋于1;交界面倾角大于60°时,轴向应变峰值降低,应变骤增节点后延并与剪应力骤降节点同步,组合体变形破坏主要取决于岩体部分;模型验证后拟合优度均高于90%。

为深入掌握采掘扰动下煤岩组合体真三轴力学特性,采用八面体剪应力理论,系统研究采掘扰动下受交界面倾角影响的煤岩组合体真三轴力学特性及能量演化机制,并最后基于德鲁克-普拉格准则,建立考虑交界面倾角影响的煤岩组合体真三轴损伤本构模型。结果表明:开挖扰动阶段,煤岩组合体轴向应变随时间线性增长,能量主要转化为弹性能,随着应变增大耗散能逐渐增加;当交界面倾角超过60°时,剪应力明显增大且增大节点延后至开挖末期。回采阶段,试样能量主要用于变形破坏;交界面倾角小于60°时,试样在剪应力达到强度极限前会发生2次变形,回采扰动末期应变有2个骤增节点,随后剪应力骤降,耗散能比例趋于1;交界面倾角大于60°时,轴向应变峰值降低,应变骤增节点后延并与剪应力骤降节点同步,组合体变形破坏主要取决于岩体部分;模型验证后拟合优度均高于90%。

To deeply understand the true triaxial mechanical characteristics of coal-rock combinations under mining disturbance, the octahedral shear stress theory was adopted to systematically study the true triaxial mechanical characteristics and energy evolution mechanism of coal-rock combinations affected by the interface inclination angle during mining disturbance. Finally, based on Drucker-Prager criterion, a true triaxial damage constitutive model for coal-rock combinations considering the influence of the interface inclination angle was established. The results show that during the excavation disturbance stage, the axial strain of the coal-rock combination increases linearly with time. The energy is mainly converted into elastic energy, and the dissipative energy gradually increases as the strain increases. When the interface inclination angle exceeds 60°, the shear stress increases significantly, and the node of shear stress increase is postponed to the end of the excavation stage. During the mining stage, the energy of the specimen is mainly used for deformation and failure. When the interface inclination angle is less than 60°, the specimen undergoes two deformations before the shear stress reaches the strength limit. At the end of the mining disturbance, there are two sudden increase nodes in strain, and then the shear stress drops sharply, with the proportion of dissipative energy approaching 1. When the interface inclination angle is greater than 60°, the peak value of axial strain decreases, the sudden increase node of strain is postponed and is synchronized with the sudden drop node of shear stress, and the deformation and failure of the combination mainly depend on the rock mass part. After model verification, the goodness of fit is higher than 90%.
