摘　　要：借助当前先进的数字化矿业DIMINE软件对七宝山铅锌矿露天矿山+105m台阶至+145m台阶的局部境界进行优化。以当量地质品位理论为基础,将矿体中共生或伴生的有用组分换算成主元素的当量品位对该矿山境界内矿石界线进行了重新圈定,优化结果表明可使矿山境界内蕴含的有限矿石资源得到充分利用。The paper introduces the optimization of the local boundary from the 105-meter step to the 145-meter step in an-open pit mine with the aid of the current advanced DIMINE digital mining software on the basis of equivalent geological grade theory,redrawing the ore boundary in the mine boundary by converting the useful components coexisting or associated with the ore body into the equivalent grade of the main elements,whose results show that the limited ore resources contained in the mine boundary can be fullyutilized.
