摘　　要：针对塔拉壕矿3203辅运巷围岩稳定与支护问题,通过现场实测和数值模拟分析了辅运巷的围岩变形破坏特征及其机理。结果表明:在工作面后方,巷道围岩开始出现变形破坏,随着工作面推进,破坏程度逐渐变大,当工作面推进300~400m后,巷道围岩开始趋于稳定。为防止发生冒顶事故,根据辅运巷顶板塑性破坏规律,提出了顶板分类补强支护措施,选择合理补打锚索、架棚支护等支护措施,以保证巷道安全。According to problems of 3203 auxiliary transport roadway surrounding rock stability and supporting in Talahao Coal Mine,through field measurement and numerical simulation,deformation and failure characteristics and mechanism of the auxiliary transport roadway surrounding rock are analyzed. The results show that, the roadway surrounding rock deformation and failure begins to appear behind the working face,as the working face advances forward,the degree of destruction becomes larger,after advancing 300 m ~ 400 m,surrounding rock of the roadway tends to be stable. In order to prevent the accidents,according to the plastic damage law of auxiliary transport roadway roof,the reinforcement measures for roof classification are put forward,reasonable support measures are applid such as adding anchor and shed supporting to ensure the roadway safety.
