摘要
采用力学分析和钢筋混凝土构件计算方法 ,设计玉水硫铜矿 70 5号采场大跨度人工假底 ,并应用于两个中段联合开采的人工假底干式充填法。结果表明 ,采用钢筋混凝土人工假底 ,多回收铜金属 3 66 93t,直接经济效益 3 5 2 3 1万元。大跨度的钢筋混凝土假底的设计与施工经验 。
The long span reinforced artificial bottom is designed and built in 705 stope Yushui Sulphur-copper Mine by mechanical analysis and calculation of reinforced concrete structure, and applied to artificial bottom-dry filling mining process The results show that copper recovery increased by 366 93t and directly economical profit is 3 5231 Million yuan RMB The design and construction experience of long span reinforced artificial bottom can be used in some similar mines for reference
