本文叙述了地质统计学的矿石储量估算方法与其他三种传统方法——多边形法、距离倒数平方法(IDS)以及同距离倒数平方法相类似的一种修正法(ELIP)的对比研究结果。用上述各种方法对亚利桑那州图克逊市附近的碧玛铜矿在同一个阶段中的各块段的品位子测结果,检验了每种方法的精确度。从碧玛铜矿的对比结果表明:在予测块段品位和矿石总吨量方面,地质统计学方法与ELIP法或IDS法相比较不差土下,而多边形法则显然最差。但如果在块段模型中已经考虑并包含了矿体的地质因素,则上述所有方法都能获得较好的结果,对于已经在生产的矿山来说,选用ELIP法或IDS法可能是比较好的,因为这两种方法占用电子计算机的时间较少,可以显著地节省运算费用。对于一个勘探的矿区或新矿区来说,由于地质统计学方法能够给出估算值的置信限,因而选用这种方法就具有更多的优越。
This paper describes the results of a comparative study of the geochemical statistic ore reserves estimation method with one of the other three conventional methods, the polygon method, the distance reciprocal method (IDS), and the similar method of distance eluting method (ELIP). Using the various methods described above, the sub-test results of the grade of each block in the same stage at the Bima copper deposit near the city of Tuxton, Arizona examined the accuracy of each method. The comparison of the results from the Bima copper mine shows that the geostatistical method is not worse than the ELIP method or the IDS method in predicting the grade of the block and the total tonnage of ore, while the polygon rule is apparently the worst. However, all of the above methods can achieve better results if the geological factors of the ore body are already considered and included in the block model. For the mines already in production, it may be better to use the ELIP method or the IDS method , Because these two methods take less time on the computer, can significantly reduce computing costs. For an exploration site or a new site, this method has more advantages because geostatistics can give confidence limits for the estimates.
