SD法在西藏甲玛铜多金属矿床资源量估算中的应用

The application of the SD method to the resource estimation of the Jiama copper-polymetallic deposit in Tibet

摘要: SD(最佳结构曲线断面积分储量计算和储量审定计算)法诞生于20世纪80年代，是在对传统法和样条函数法改进并与距离幂次反比法等方法结合的基础上发展起来的新方法，在储量估算领域内具有一定的先进性。多金属矿多种元素共生的情况使资源量的计算变得复杂。对西藏甲玛铜多金属矿使用SD法和平行断面法进行资源量估算，结果对比证明SD方法能较好地适用于多金属矿的资源量计算。

Abstract: Established in the 1980′s, the SD method has been widely used in reserve calculation because of its combination of dynamic fractal geometry and structural geological variable theory. Reserve calculation is complicated due to mineral intergrowth. Compared with traditional methods used in copper polymetallic mine reserve calculation, the SD method shows better performance.
