摘　　要：为提高矿产储量计算的精确性,本文运用了限制性克立格法。给出了限制性克立格法的计算理论,并设计出限制性克立格法在阿舍勒铜矿中的储量计算流程,实现了对阿舍勒铜矿体的限制性克立格储量计算。结果表明,限制性克立格法的储量计算结果(783654.39t)要比普通克立格法的储量计算结果(706541.53t)更接近于实际勘探值(919454t),限制性克立格储量计算方法能够取得较为理想的预测结果。This research applied Restricted Kriging （RK） to improve the accuracy of calculation of reserves. Its computational theory was given and the procedure of calculation of reserves was designed. This calculation was realized with RK. It is shown that the result of calculation of reserves is 783 654.39 t with RK, which is closer to the actual value 919 454 t than the result 706 541.53 t with Common Kriging （CK）. The fact shows that the RK can produce better mineral prediction.
