摘　　要：针对传统矿产储量计算方法和地质统计学矿产储量计算方法存在的不足,提出了一种均值与插值相结合的新的矿产储量计算方法。该方法先建立网格,再将网格分成内部包含样品和内部不包含样品两类,然后分别用平均值法和距离平方反比法计算其品位值,进而得出网格乃至整个矿体的储量。这种储量计算方法既解决了传统算法准确度不够高的缺点,又克服了地质统计学方法计算量太大的弊端。对紫金山金矿床某矿体储量的实际计算结果证明了新算法的可行性。In view of the defects in the conventional mineral reserve calculation method and geostatistical mineral reserve calculation method, a new mineral reserve calculation method that combines mean value and interpolation methods is proposed. This method first sets up the grids, divides the grids into two categories ： containing samples or not, calculates their grade values by mean value method and inverse distance square method respectively, and further obtains the reserve of the grids and also of the whole orebody. This reserve calculation method can not only solve the problem of not high accuracy of the conventional algorithm but also eliminate the drawback of a too much calculation work involved in geostatistical method. The feasibility of the new algorithm has been proved in the practical calculation of the reserve of an orebody in Zijinshan gold deposit.
