中文摘要:
      通过分析深部铜矿破碎地段支护失效的原因,通过建立巷道开挖岩石力学分析模型,对巷道开挖后的破碎圈半径和应力分布进行了计算,根据计算结果,对破碎地段的巷道支护参数进行了设计计算,设计采用钢筋混凝土和锚杆联合支护方案,混凝土厚度95cm,锚杆长度2m,新的支护方案对破碎地段的巷道支护效果明显。
英文摘要:
      By analyzing the reason of failure of support in the fractured section of deep copper mine, through the establishment of rock mechanics analysis model of roadway excavation, the radius and stress distribution of the breaker ring after tunnel excavation was calculated. According to the calculation results, the roadway in the broken section was analyzed. The support parameters were designed and calculated. The design of reinforced concrete and bolt joints was adopted. The concrete thickness was 95cm and the length of the anchor bolt was 2m. The new support scheme had obvious effect on roadway support in the fragmented section.
