摘　　要：金川二矿区的巷道工程在其服务期限间,变形破坏比较严重,巷道的维护量居高不下,对生产安全和采矿成本的控制都有重要影响。要解决这些问题,还需真正掌握地压的分布规律和围岩与支护的协调适应关系,在此基础上才能提出合理可靠的支护形式、结构和强度。During the service life of the tunnel in Jinchuan No.2 mining area,the deformation and damage of tunnel are rela-tively serious,and the maintenance amount of tunnel is high,which imposes an important impact on production safety and mining cost control.To solve these problems,it is also necessary to truly master the distribution law of ground pressure and coordination and adaptation of surrounding rock and support.On this basis,a reasonable and reliable support form,structure and strength can be pro-posed.

关 键 词：金川二矿区 巷道工程 变形破坏 可靠支护
