In order to evaluate the surrounding rock stability of deep roadways, the diversity of accident hazard sources in deep coal mining is statistically analyzed. To conduct an effective evaluation, first, the risk analysis of the factors affecting the rock mass accidents is carried out, and the comprehensive safety index system of rock accidents in deep mine roadway is established. Further, combining the theory of hazard sources with the extension method, a matter-element model for the risk assessment of rock mass accidents in deep roadway is established. Finally, the hazard sources for the surrounding rock stability of deep roadway in the E-Zhuang coal mine of Xinwen Ming area are evaluated. The results show that the risk grade of the surrounding rock for deep roadways in E-Zhuang coal mine is "B", which is generally safe, the human factors and organizational management factors are relatively safe, and some suggestions for improvement are put forward.
为了评估深部巷道围岩的稳定性，对深井煤矿事故危险源的多样性进行了统计分析。为了进行有效评估，首先对影响岩体事故的因素进行风险分析，建立深部矿井巷道岩爆综合安全指标体系。进一步地，结合危险源理论和可拓方法，建立了深部巷道围岩岩爆风险评价的物元模型。最后，对新汶矿区 E-Zhuang 煤矿深部巷道围岩稳定性的危险源进行了评价。结果表明，E-Zhuang 煤矿深部巷道围岩的风险等级为“B”，总体安全，人为因素和组织管理因素相对安全，并提出了一些改进建议。
