摘要
千家坪钒矿矿体与围岩均不稳固,矿体厚度属中厚,倾角属急倾斜,不适合空场法开采;充填法主要针对高品位有色金属、富品位贵金属和稀有贵重金属,钒矿石品位低,从经济角度讲也不符合充填法开采;崩落法是在崩落围岩下出矿,贫化率极高,也不适合采用。选择低阶段垂直扇形深孔无底柱空场法,目前看来不失为经济、有效、实用的采矿方法。
The ore body and surrounding rock Qianjiaping vanadium mine are not stable,the thickness of ore body is thick,is a steep dip,not suitable for stope mining; filling method mainly for high grade non-ferrous metals,rich taste of precious metals and rare precious metals,vanadium ore grade is low,from an economic point of view is not consistent with the backfill mining caving; law is the ore rock in caving,the dilution rate is extremely high,is not suitable for use. Choose the low stage vertical deep hole sector nonpillar sublevel open stope method,it is economical and effective mining method.
