The plastic zone range is an important parameter in the analysis of damage characteristics and the degree of damage to the rock surrounding a roadway. Based on the establishment of a plastic zone calculation model considering the creep effect, this paper obtains the characteristics of the change in the plastic zone damage range with time by solving the model. Additionally, the validity of the model is verified by field experiments. The research results can provide guidance for gas pressure measurement and gas drainage in coal mines.

考虑蠕变效应的巷道塑性区范围

塑性区范围是分析破坏特征和对巷道周围岩石破坏程度的重要参数。在建立考虑了蠕变效应的塑性区计算模型的基础上，通过求解模型获得了塑性区损伤范围随时间变化的特征。此外，该模型的有效性通过现场实验得到了验证。研究结果可为煤矿瓦斯压力测量和瓦斯抽采提供指导。
