摘要
通过对四川泸沽铁矿大顶山矿区软弱破碎地段巷道变形失稳机理的分析 ,对该矿的矿岩进行分类 ,采用分级支护等措施 ,对该矿井巷支护技术进行了优化 ,大大提高了成巷率 ,为矿山生产创造良好条件。
Based on the analysis of unstable mechanism due to deformation of the tunnel in the soft broken section of Dadingshan Mine zone of Sichuan Lugu Iron Mine,the mine rock of the Mine is classified.The support technology of mine workings of the Mine is optimized by the stage support measure,which greatly increases qualification rate and gives a favourable condition for the Mine production.
