摘　　要：大孤山铁矿西端矿石井巷道内出现多处环向通体裂缝,顶棚局部衬砌出现坍塌、断裂、掉渣现象。对衬砌开裂现象进行调查,总结其开裂规律,对裂缝成因进行定性评价,最后提出处理加固裂缝的措施。The mine tunnel of dagushan iron mine appears many crosswise through cracks, the localized lining of the ceiling ap- pears fracture and abscission. This article carries on the investigation to its dehiscence phenomenon, summarizes its dehiscence regularity, and takes qualitative analysis to the genesis of cracks, finally presents the measures of reinforcement of the cracked areas.
