摘要
介绍了金川二矿区围岩的工程地质分类、地应力的分布规律和不良岩层围岩的基本特征,总结了金川二矿区深部巷道的变形破坏规律,评价了过去该矿所用的各种巷道支护方式,并介绍了金川二矿区深部巷道支护的新方法。
This paper presented the engineering geological classification, ground stress distribution law and the basic_characters of poor surrounding rock.The deep roadway deformation law in Jinchuan No.2 mining area was summarized. The previous roadway support ways were reviewed. In the end, the new support method of deep roadway was introduced.
