此文为GDMB(德意志矿冶工作者协会)研究小组用地质统计法进行储量分级的中期成果报告与1982年2月2日就此分级方法在迪赛尔多夫(Dusseldorf)举行的学术讨论会概要。 GDMB研究小组建议: ——选择对矿床的经济评价最为敏感的参数作为储量分级的基本参数; ——按固定的置信度(90％)及可变的误差限来划定储量的级别(见表2); ——将可采3至5年的“核心储量”定义为“定级块段”储量; ——根据各自的离差外延,计算地质数理统计学方面的误差限。
This is the interim results report of the GDMB (German Association of Mining and Metallurgical Workers) Reserves Gradation by Geostatistics and the summary of the Symposium held in Dusseldorf on February 2, 1982, on the grading methodology . The GDMB team recommends: - choosing the most economically sensitive parameters of the deposit as a basic reserve grading parameter; - determining the level of reserves by a fixed confidence level (90%) and a variable error limit (see table 2); - Define the “core reserves” that can be extracted for 3 to 5 years as reserves of the “Rating Blocks”; - Calculate the error limits of geo-mathematical statistics according to their respective dispersion extensions.
