摘　　要：为解决复杂地质条件下程潮铁矿巷道的稳定性问题，利用FLAC-3D软件进行计算和分析，发现在破碎带贯穿巷道的情况下，破碎带与巷道中垂线夹角呈30～60°时对围岩稳定性影响最大，同时提出锚杆联系链巷道支护方案，为矿山安全生产提供了保证。To solve the stability problem of the roadway in com- plicated geological conditions in Chengchao Iron Mine, calculation and analysis made using FLAC-3D software found that with a bro- ken belt across the roadway, included angle between the broken belt and the perpendicular bisector of the roadway at 30 -60 ° has the greatest impact on the stability of surrounding rocks. A/so, the support scheme with bolt connection chain to the roadway is proposed to provide a guarantee for safety in mine operation
