摘　　要：针对太和铁矿急倾斜矿体的特点(急倾斜矿体),分析了在露天开采过程中,矿体顶板脉外开沟、矿体脉内开沟、采矿工作面推进方式以及矿体内夹石所引起的矿石损失和品位贫化的原因。通过图解分析方法,将复杂的问题简单化,较为清楚的说明了以上因素与矿石损失、贫化之间的内在联系及规律,提出了降低矿石损失与贫化的措施。In view of the characteristics of steep inclined ore-body in Taihe iron mine, the causes for ore loss and dilution resulting from roof cutting outside ore body vein, cutting within the ore body vein, mining work face advancing and horse stone in ore body etc. were analyzed. Through the graphic analysis method, complicated prob- lems were simplified, the inner connection and law of above factors and ore dilution and loss were made clear, and the measures for reducing the ore loss and dilution were put forward.
